What is the greatest common factor of 45 and 5?
The GCF of 5 and 45 is 5Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and 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 45 are 1, 3, 5, 9, 15, and 45.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The GCF/HCF of 5 and 45 is 5.
What is the common factor of 18 and 45?
The greatest common factor of 18 and 45 is 9.
What is the greatest common divisor of 18 and 45?
The Greatest Common Divisor of 18, 45 is 9.
What is the greatest common factor of 9 18 and 45?
9 is a factor of both 18 and 45, and is the largest factor of itself, so 9 is the greatest common factor.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 9 are 1, 3, and 9.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 45 are 1, 3, 5, 9, 15, and 45.The common factors are 1, 3, and 9. Therefore, 9 is the greatest common factor.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 9 are 3 and 3.The prime factors of 18 are 2, 3, and 3.The prime factors of 45 are 3, 3, and 5.The prime factors they all have in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.WHAT? evry gcf # has to be PRIME only? HELP!!!!!!!!

What are the common factors and greatest common factor of 45?
Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 45, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.Examples:The common factors of 18 and 45 are 1, 3, and 9; the greatest common factor is 9.The common factors of 25 and 45 are 1 and 5; the greatest common factor is 5.
