One way to approach this is to look at the difference between 72 and 80, which is 8. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. Since both 72 and 80 are divisible by 8, the greatest common factor is 8. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. 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 72 are 2, 2, 2, 3, and 3. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.
The GCF is 8.
48 has ten factors, 60 and 72 have twelve apiece, 80 is the next one with exactly ten.

72/80 x 100 = 90 % 100 - 90 = 10 % which is the decrease from 80 to 72
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. All of the factors of 36 are also factors of 72.
Since 36 is a factor of 72, the factors of 36 are included in the factors of 72.
