Express 16 as a product of prime factors?

To express 16 as a product of prime factors, we first note that 16 is an even number, so we can divide it by 2. 16 divided by 2 equals 8. 8 is also divisible by 2, so we divide it by 2 again to get 4. Finally, 4 is divisible by 2, giving us 2 x 2 x 2 x 2, or 2^4. Therefore, 16 can be expressed as 2^4.

What is the factor tree for 188?

To find the factor tree for 188, we start by identifying two factors of 188 that multiply to give 188. One possible pair is 4 and 47. Then, we continue factoring these numbers until we reach their prime factors. The factor tree for 188 would be:

188 /
4 47 /
2 2 47

Therefore, the prime factorization of 188 is 2 x 2 x 47.

What is the highest common factor of 756?

Oh, dude, the highest common factor of 756? That's like the biggest number that can divide 756 without leaving a remainder. So, the highest common factor of 756 is 756 itself. It's like the king of factors for that number.

What is the LCM of 27 84 and 90?

Oh, dude, like, the least common multiple (LCM) of 27, 84, and 90 is 756. It's basically the smallest number that all three of those numbers can divide into evenly. So, if you're ever at a party and someone asks you for the LCM of 27, 84, and 90, you can totally impress them with that number.

What is the greatest common factor of 24 and 32 and 48?

To find the greatest common factor (GCF) of 24, 32, and 48, we need to determine the largest number that divides evenly into all three numbers. First, we find the factors of each number: 24 (1, 2, 3, 4, 6, 8, 12, 24), 32 (1, 2, 4, 8, 16, 32), and 48 (1, 2, 3, 4, 6, 8, 12, 16, 24, 48). The GCF of 24, 32, and 48 is 8, as it is the largest number that appears in the factor lists of all three numbers.

Express 650 as the product of prime factors?

To express 650 as the product of prime factors, we first divide it by the smallest prime number, which is 2. This gives us 325. Then, we divide 325 by 5, another prime number, to get 65. Continuing this process, we divide 65 by 5 to get 13, which is a prime number. Therefore, the prime factorization of 650 is 2 x 5 x 5 x 13.

What is the gcf of 27y and 54y3?

Since 27y is a factor of 54y3, it is automatically the GCF.

What is 44's prime factorization using exponents?

The prime factorization of 44 using exponents is 2^2 x 11. This means that 44 can be expressed as the product of 2 raised to the power of 2 (2^2) and 11. In other words, 44 = 2 x 2 x 11. This representation helps break down the number into its prime factors for easier analysis and computation.

How do you write 128 in expanded notation using exponents?

Sure thing, honey. To write 128 in expanded notation using exponents, you'd express it as 1 x 10^2 + 2 x 10^1 + 8 x 10^0. So, it would be 1 x 100 + 2 x 10 + 8 x 1. Easy peasy lemon squeezy.

What is the GCF of 90 and 180?

The Greatest Common Factor (GCF) of 90 and 180 is 90. To find the GCF, you can list the factors of each number and determine the largest number that divides both numbers evenly. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180.
