49 = 7 * 7 56 = 7 * 2 * 2 * 2 The common factor is 7 -- greatest or least is the same in this case. greatest common factor of 56 and 49 is 7. 56 = 7 * 2 * 2 * 2 49 = 7 * 7 7 56 / 49 = 1 r 7 49 / 7 = 7 r 0
The GCF is 7.
Let us find the Highest Common Factor (HCF) for 49 and 56: We know that, The factors of 49 are 1, 7, 49 The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56 So, the highest common factor of 49 and 56 is 7.
It is: 7
The greatest common factor of 39 and 156 is 39.
Factors of 49: 1, 7, 49Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56GCF (49, 56) = 7
The GCF is 7.
The GCF is 1.
56
The GCF is 1.
The least common factor of any set of integers is 1.
The greatest common factor of 161 and 105 is the same as the greatest common factor of 105 and 56. I obtained the number 56 by subtracting 161 - 151. Continue like this, until you get one number that is an exact multiple of the other. The next step is, 105 - 56 = 49, so you have to calculate the gcf of 56 and 49. This method is known as Euclid's Algorithm.
