What is the greatest common factor of 17 and 21?
The GCF of 17 and 21 is 1Definition: 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 17 are 1 and 17.The factors of 21 are 1, 3, 7, and 21.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.1 because 17 is a prime number
