Given numbers are 130, 646, 851, 171

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 646 are 2 x 17 x 19

Prime factors of 851 are 23 x 37

Prime factors of 171 are 3 x 3 x 19

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

Given numbers are 130, 646, 851, 171

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

Apply this formula for all numbers.

Step1:

LCM(130, 646) = 41990

GCD(130, 646) = ( 130 x 646 ) / 41990

= 130 / 646

= 130

Step2:

LCM(2, 851) = 1702

GCD(2, 851) = ( 2 x 851 ) / 1702

= 2 / 851

= 2

Step3:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

So, Greatest Common Divisor of 130, 646, 851, 171 is 1
