The greatest common factor of 78 , 8 = 2
The greatest common factor of 2 , 8 , 42 , and 70 = 2
The greatest common factor of 2 and 8 is 2. If one number is a multiple of the other, the smaller number is the greatest common factor, because it is the largest possible factor of itself. Since 8 is a multiple of 2, the greatest common factor is 2. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 2 are 1 and 2. The factors of 8 are 1, 2, 4, and 8. The factors in common are 1 and 2. Therefore the greatest common factor of 2 and 8 is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 2 is 2. The prime factors of 8 are 2, 2, and 2. The prime factors in common are a single 2, so the greatest common factor is 2.
The GCF of 8 and 24 is 8.The factors of 8 are 1, 2, 4, and 8.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8.The greatest common factor can also be determined from the prime factors.The prime factors of 8 are 2, 2, and 2.The prime factors of 24 are 2, 2, 2, and 3.The prime factors they have in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.The Greatest Common Factor is 8
