The GCF is 1.
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56 Factors of 18: 1, 2, 3, 6, 9, 18 Therefore, greatest common factor (GCF) of 56 and 18: 2
The Greatest Common Factor (GCF) is: 9
The Greatest Common Factor (GCF) is: 9
The greatest common factor of 9 and 25 is 1
The greatest common factor of 9 , 8 = 1
The Greatest Common Factor of 9, 23 is 1.
The greatest common factor of 9 and 620 is 1.
The greatest common factor of 9 and 618 is 3
Factors of 45: 1 3 5 9 15 45 Factors of 56 : 1 2 4 7 8 14 28 56 The GCF of 45 and 56 is 1 Another way to approach this is to look at the difference between 45 and 56, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. The greatest common factor of two numbers must also be a factor of the difference between the numbers. The difference, 11, is a prime number, so the greatest common factor must be either 11 or 1. Since the numbers are not evenly divisible by 11, the greatest common factor is 1.
The Greatest Common Factor of 81, 108, 117: 9
The Greatest Common Factor of 60, 21, 9: 3
Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The GCF is: 4The GCF is 4.
