The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54

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 factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
1 and 2
1,2,3,6,9,18,27 and 54
Since 18 is a factor of 54, all of its factors are common.
The factors of 2 are 1 and 2 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 factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54.
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54.
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.
Since 18 is a factor of 54, all of its factors are common.
