Oh honey, 72 is like a puzzle piece that's been put together a million times. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The greatest common factor is the biggest number that can divide both 72 and another number without leaving a remainder. So, the greatest common factor of 72 is 72 itself.

CoachThere is neither a greatest common factor nor common factors of a single number, such as 72, 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.
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
The prime factors of 72 are 2, 2, 2, 3, and 3.
Examples:
The common factors of 21 and 72 are 1 and 3; the greatest common factor is 3.
The common factors of 56 and 72 are 1, 2, 4, and 8; the greatest common factor is 8.
The common factors of 72 and 100 are 1, 2, and 4;the greatest common factor i s 4.

The question has a problem, because a greatest common factor is a factor "common" to two or more numbers. A single number has no "common" factor.
An example of greatest common factor:
Find the greatest common factor of 49 and 21.
- The factors of 49 are 1, 7, and 49.
- The factors of 21 are 1, 3, 7, and 21.
The greatest factor common to both numbers is 7.

What is the greatest common factor of 27 and 72?
The greatest common factor (GCF) of 27 and 72 is 9. The common factors of 27 and 72 are 1, 3, and 9. Methods: 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 27 are 1, 3, 9, and 27. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 27 are 3, 3, and 3. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
What is the greatest common factor of 88 and 72?
The greatest common factor of 88 and 72 is 8.
What is the greatest common factor of 72 and 64?
The GCF of 64 and 72 is 8.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 greatest common factor is to find all the factors of the numbers and compare them.The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 64 are 2, 2, 2, 2, 2, and 2.The prime factors of 72 are 2, 2, 2, 3, and 3.The prime factors in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.Summary:The common factors of 64 and 72 are 1, 2, 4, and 8.The greatest common factor of 64 and 72 is 8.
What is the greatest common factor of 42 and 72?
The greatest common factor of 42 and 72 is 6 Gcf stands for Greatest Common Factor, The gcf of 42 and 72 is the largest positive number that is a factor of both 42 and 72. The positive factors of 42 (the integral divisors of 42) are: 1, 2, 3, 6, 7, 14, 21, and 42. The positive factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 36, and 72. Therefore the gcf of 42 and 72 is 6, as the greatest factor that 42 and 72 have in common.
What is the greatest common factor of 72 and 144?
The GCF of 72 and 144 is 72. Since 72 is a factor of 144, it is automatically the GCF.
