Given numbers are 851, 178, 860, 172

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 178 are 2 x 89

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 851, 178, 860, 172

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

Apply this formula for all numbers.

Step1:

LCM(851, 178) = 151478

GCD(851, 178) = ( 851 x 178 ) / 151478

= 851 / 178

= 851

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 851, 178, 860, 172 is 1
