The simplest is Euclid's method : Start with 45, 60
minimum is 45 : subtract minimum from bigger number(s): 45, 15
minimum is 15 : subtract minimum from bigger number(s): 30, 15
minimum is 15 : subtract minimum from bigger number(s): 15, 15
minimum is 15 , maximum is also 15 so GCF is 15.
3 x 3 x 5 = 45
2 x 2 x 3 x 5 = 60
Select the common factors.
3 x 5 = 15, the GCF
List the factors.
Select the largest number that appears on all three lists.
The answer will be 1.

What is the greatest common factor of 180 and 231?
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 180 and 231 is 3
What is the greatest common factor of 12 and 45?
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 22 and 45 is 1

What is the greatest common factor of 6 and 45?
The GCF of 6 and 45 is 3. 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 both numbers have in common. 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 6 are 1, 2, 3, and 6. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1 and 3. Therefore, the greatest common factor is 3.
What is the greatest common factor of 21 and 45?
The GCF of 21 and 45 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 21 are 3 and 7. The prime factors of 45 are 3, 3, and 5. The prime factors in common are a single 3, so the greatest common factor is 3.
What is the common factor of 18 and 45?
The greatest common factor of 18 and 45 is 9.
