What is the opposite of a common factor?
The opposite of a common factor is a prime factor. Common factors are numbers that evenly divide two or more integers, while prime factors are numbers that are only divisible by 1 and themselves. The prime factors of a number are the building blocks that make up that number, and they cannot be further broken down into smaller factors.
What two number make 45 the GCF?
with the numbers 90 and 45, 45 is the GCF(Greatest Common Factor).
How do you find the common factor in fraction division?
To simplify a multiplication or division involving fractions, you need to find common factors. For small numbers, you might just try to do a complete factorization of each of the numbers involved. It's best not to multiply them in the first place; it doesn't really make sense to multiply and then factorize again. For larger numbers, you can use Euclid's algorithm to find the greatest common factor.
Why does it make sense to multiply the numbers in the middle of the Venn Diagram to determine the GCF of a pair of numbers?
Factors multiply. The numbers in the middle of the Venn diagram are common factors. If there are two or more, their product will give you the greatest common factor.
Why can you make several different factor trees for some numbers but only one or two factor trees for other numbers?
Bigger numbers make bigger factor trees, and of course there are prime numbers which cant be factored at all

What is the greatest common factor of 5 and 6?
Answer:The greatest common factor of 5 and 6 is 1Methods:The greatest common factor of any pair of numbers for which the difference is 1, such as 5 and 6, must be 1. The greatest common factor cannot be larger than the difference. So, the greatest common factor of 5 and 6 is 1.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 5 are 1 and 5.The factors of 6 are 1, 2, 3, and 6.The only common factor is 1 . Therefore, the greatest common factor is 1.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 5 is 5.The prime factors of 6 are 2 and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.the greatest common factor of 6 and 5 is 1The GCF is 1.i think it is safe to say it is 30. I cant think of any other number that 5 and 6 both go into.
What are the numbers that 63 can be divided by that can also be multiplied to make 33?

How do you make a factor?
A factor of a certain number in Mathematics are the numbers that can be divided by the original number.
Can a fraction be simplified if it doesn't have a common factor?
No! because the common factor divides both part to make it simpler.
Why you would never be asked to find the least common factor of a pair of numbers?
You would never be asked to find the least common factor of a pair of numbers because factors are the numbers that can be multiplied together to get a specific number, and the least common factor of any pair of numbers is always 1. This is because 1 is a factor of every number and is the smallest positive integer. Therefore, finding the least common factor of a pair of numbers would always result in 1, making it unnecessary to calculate.
What are two numbers whose GCF is 20?
Two numbers whose greatest common factor (GCF) is 20 are any pair of numbers that are multiples of 20. For example, 20 and 40 have a GCF of 20 because 20 is a factor of both numbers. Another pair could be 60 and 80, as 20 is also a factor of both of these numbers.
