Answer: 1
Definition: 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 25 are 1, 5, and 25.
The factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189.
The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
The greatest common factor of 25 and 100 is 25.
The greatest common factor (GCF) is 25.
The greatest common factor of 25 and 175 is 25.
The greatest common factor (GCF) is 25.
The greatest common factor of 25 and 76 is 1.
The greatest common factor of 25 and 34 is one.
The greatest common factor of 9 and 25 is 1
The greatest common factor of 25 and 33 is 1.
The greatest common factor of 25 and 80 is 5.
The greatest common factor of 140 and 25 is 5.
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
The Greatest Common Factor of 25, 125, 200: 25
