What is the least common multiple of 70 and 175?

Oh, what a happy little math question! To find the least common multiple of 70 and 175, we can start by finding the prime factors of each number. The prime factors of 70 are 2, 5, and 7, and the prime factors of 175 are 5, 5, and 7. Then, we can multiply the highest power of each prime factor together to find the least common multiple, which in this case is 2 x 5 x 5 x 7 = 350.

What equals 100?

There are many mathematical equations that equal 100, such as 50+50, 10^2, 200-100, and 4*25. In algebraic terms, x could equal 100 when x=100. Additionally, in terms of percentages, 100% is equivalent to 100.

What are the first two common multiples of 2 3 and 7?

To find the common multiples of 2, 3, and 7, we first list the multiples of each number:
Multiples of 2: 2, 4, 6, 8, 10, 12, ...
Multiples of 3: 3, 6, 9, 12, 15, 18, ...
Multiples of 7: 7, 14, 21, 28, 35, ...
The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.

What is the greatest common factor of 54 and 84?

The GCF of 54 and 84 is 6.

step 1: list all of the prime numbers that go into 54 and 84.

2*3*3*3=54

2*2*3*7=84

step 2: find the common prime numbers between both sets.

2*3*3*3=54

2*2*3*7=84

2*3

step 3: multiply your answer.

2*3=6

6 is the greatest common factor

What is the greatest common factor of 3 and 36?

The greatest common factor (GCF) of 3 and 36 is 3. This is because 3 is a factor of both 3 and 36, and it is the largest factor that they have in common. To find the GCF, you can list the factors of each number and identify the largest one they share.

What number equals 68 in multiplication?

Oh, dude, you're hitting me with some math right now? Okay, so technically, any number multiplied by 1 will equal itself, so 68 divided by 1 is... 68. But like, you could also say 34 multiplied by 2 equals 68. Math, man, it's wild.

What is a factor of 75 bigger than 20 but smaller than 30?

Can the greatest common factor of 16 and 42 be less than 16?

Yes. The greatest common factor of 16 and 42 must be a factor of 16.

The only rule is that the GCF has to be equal to or less than the lower number. Since 16 is not the GCF of 16 and 42, the GCF has to be lower than 16.

What are three factors whose product is about 10000?

Three factors whose product is about 10000 are 25, 20, and 20. This is because 25 x 20 x 20 = 10000. Another set of factors could be 50, 10, and 20, as 50 x 10 x 20 also equals 10000. In general, factors that are close to the cube root of 10000 (which is approximately 21.54) will have a product close to 10000.
