Given numbers are 645, 101, 931, 501

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 101 are 101

Prime factors of 931 are 7 x 7 x 19

Prime factors of 501 are 3 x 167

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 645, 101, 931, 501

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(645, 101) = 65145

GCD(645, 101) = ( 645 x 101 ) / 65145

= 645 / 101

= 645

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 501) = 501

GCD(1, 501) = ( 1 x 501 ) / 501

= 1 / 501

= 1

So, Greatest Common Divisor of 645, 101, 931, 501 is 1
