The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
-3 + 4 - 6 + 3 - 2 + 42 = 1 - 6 + 3 - 2 + 42 = - 5 + 3 - 2 + 42 = - 2 - 2 + 42 = - 4 + 42 = 38
gcf(54, 30, 42) = 6 54 = 2 x 3^3 30 = 2 x 3 x 5 42 = 2 x 3 x 7 hcf = 2 x 3 = 6
The common factors of 42 and 54 are: 1, 2, 3, and 61, 2, 3 and 6.
If that's 6 and 42/54, find the GCF of 42 and 54. When you find out that the GCF is 6, divide them by it. The answer is 6 and 7/9.
1, 2, 3 and 6.
1, 2, 3 and 6
1, 2, 3 and 6
6 is the GCF for 42 and 54.
42/6 + 2*3 = 7+6 = 13
42
The greatest common factor of 42, 54, and 78 is 6. 54 = 2 x 3^3 42 = 2 x 3 x 7 78 = 2 x 3 x 13 So the highest common factor is 2 x 3 = 6
