Given numbers are 860, 646, 431, 477

The list of prime factors of all numbers are

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 431 are 431

Prime factors of 477 are 3 x 3 x 53

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

Given numbers are 860, 646, 431, 477

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

Apply this formula for all numbers.

Step1:

LCM(860, 646) = 277780

GCD(860, 646) = ( 860 x 646 ) / 277780

= 860 / 646

= 860

Step2:

LCM(2, 431) = 862

GCD(2, 431) = ( 2 x 431 ) / 862

= 2 / 431

= 2

Step3:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

So, Greatest Common Divisor of 860, 646, 431, 477 is 1
