20/27 Solution Method: 40 = 2*2*2*5 (<-- these are the factors of 40) --- 54 = 2*3*3*3 (<-- these are the factors of 54) The only common factors in both the numerator & the denominator are 2. That means you can divide 40 by 2 & 54 by 2 to get 20/27.
The common factors of 12 and 54 are 1, 2, 3, and 6.
54
The common factors of 60 and 54 are 1, 2, 3, and 6.
Common factors of 36 and 54 are: 1, 2, 3, 6, 9, and 18.

One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The common factors are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 40 are 2, 2, 2, and 5. The prime factors of 54 are 2, 3, 3, and 3. The prime factors in common are a single 2, so the greatest common factor is 2.
Common factors of 54 and 22 are: 1 and 2.
The common factors of 32 and 54 are: 1 and 2
The common factors of 54 and 75 are 1 and 3.
Since 54 is a factor of 108, all of 54's factors are common and the GCF is 54 itself.
The common factors of 54 and 63 are: 1, 3, and 9
The common factors of 45 and 54 are: 1, 3, and 9
Since 18 is a factor of 54, all of its factors are common.
The common factors of 42 and 54 are: 1, 2, 3, and 6
The common factors of 28 and 54 are: 1, 2
