What is the highest common factor of 84 and 154?

Oh, dude, you're hitting me with some math vibes. So, like, the highest common factor of 84 and 154 is 14. It's like the biggest number that can divide both of them without leaving a remainder. So, yeah, 14 is the magic number here.

Which is bigger .34 fl.oz or .5 fl. oz?

To determine which is bigger between .34 fl. oz and .5 fl. oz, we can convert both values to a common denominator. Since both values are in fluid ounces, we can directly compare them. In this case, .5 fl. oz is larger than .34 fl. oz because .5 is greater than .34.

Is prime factorization an NP-complete problem?

Yes, prime factorization is not an NP-complete problem. It is in fact in the complexity class NP, but it is not known to be NP-complete.

How can you prove that a set is infinite?

A set can be proven to be infinite if it can be put into a one-to-one correspondence with a proper subset of itself. This means that there is a way to match each element in the set with a unique element in a subset, showing that the set has an endless number of elements.

How can one demonstrate that a set is infinite?

One can demonstrate that a set is infinite by showing that it can be put into a one-to-one correspondence with a proper subset of itself. This means that the set can be matched with a part of itself without running out of elements, indicating that it has an infinite number of elements.

How would finding the Lcm help you when dividing items into equal groups?

Finding the least common multiple (LCM) would help when dividing items into equal groups by ensuring that each group receives an equal number of items without any remainders. By determining the LCM of the total number of items and the number of groups, you can divide the items evenly among the groups. This method helps to avoid any discrepancies in the distribution of items and ensures a fair division process.

What is the HCF of 55 and 77 and 132?

The Highest Common Factor (HCF) of 55, 77, and 132 is the largest number that divides all three numbers without leaving a remainder. To find the HCF, you can first find the prime factors of each number: 55 = 5 x 11, 77 = 7 x 11, and 132 = 2^2 x 3 x 11. Then, identify the common prime factors among the numbers, which are 11. Therefore, the HCF of 55, 77, and 132 is 11.

What are numbers called with only one factor?

Numbers with only one factor are called prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. Examples of prime numbers include 2, 3, 5, 7, 11, and so on. These numbers have only two factors: 1 and the number itself.

What is the HCF of 210 and 112?

The Highest Common Factor (HCF) of 210 and 112 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 210 is 2 x 3 x 5 x 7, and the prime factorization of 112 is 2^4 x 7. The common factors are 2 and 7, so the HCF is 2 x 7 = 14.

What is the gcf of 34 and 51 and 85?

To find the greatest common factor (GCF) of 34, 51, and 85, we first need to find the prime factorization of each number. The prime factorization of 34 is 2 x 17, 51 is 3 x 17, and 85 is 5 x 17. The common factor among these three numbers is 17, making the GCF of 34, 51, and 85 equal to 17.

X2 - 16x plus 28?

Oh, dude, you've thrown me back to high school math class with that one. So, X2 - 16x + 28 is a quadratic expression that can be factored as (X - 14)(X - 2). That's like the math version of solving a puzzle, but like, who even uses this stuff in real life, am I right?

What equals 103?

103 can be expressed as the sum of two prime numbers (53 + 50) or the product of two prime numbers (17 x 6 + 1). It can also be written as the cube of the fourth prime number (2^3 + 11^3) or as the sum of consecutive numbers (51 + 52).

How do you factor the polynomial 2x 16?

To factor the polynomial 2x^2 + 16, we first look for a common factor. In this case, both terms are divisible by 2, so we can factor out a 2 to get 2(x^2 + 8). Next, we check if the remaining quadratic expression x^2 + 8 can be factored further. Since x^2 + 8 cannot be factored further over the real numbers, the factored form of the polynomial is 2(x^2 + 8).

What is x to the 2nd power minus x minus 56?

x^(2) - x - 56

is a Quadratic EXPRESSION.

This can be factored to

( x + 7)(x - 8)

To find the values of 'x' , it needs to be equated to 'zero'

Hence it is Quadratic EQUATION

x^(2) - x - 56 = 0

( x + 7)(x - 8) = 0

x + 7 = 0

x = -7

& / or

x - 8 = 0

x = 8
