To find the greatest common factor (GCF) for 21, 35, and 56, we need to first find the prime factors of each number. The prime factors of 21 are 3 and 7, 35 breaks down to 5 and 7, and 56 can be expressed as 2, 2, 2, 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 7. Therefore, the greatest common factor for 21, 35, and 56 is 7.
Greatest Common Factor= 1
The GCF is 7.
The factors of 21 are: 1, 3, 7, 21The factors of 35 are: 1, 5, 7, 35The common factors are: 1, 7
The greatest common factor is 5, so 15/35 = 3/7. 3 and 7 are prime; this cannot be reduced any further.
Factors of 35 are: 1, 5, 7, 35Factors of 49 are: 1, 7, 49So, the highest common factor is 7.
7
The greatest common factor (GCF) is: 7.7
The GCF is 7.
The GCF of 21, 35, and 63 is 7.
21 = (3)(7)35 = (5)(7)7
The GCF is 1.
The GCF is 7.
The GCF is 7.
The greatest common factor of 7, 35 and 49 is 7.
The factors of 21 are:1, 3, 7, 21The factors of 35 are:1, 5, 7, 35The common factors are:1, 7The Greatest Common Factor:GCF = 7
The greatest common factor of 35 and 125 is 5.The greatest common factor of the numbers 35 and 125 is 5.
GCF(21, 5, 35) = 1
