Given numbers are 651, 519, 646, 406

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 519 are 3 x 173

Prime factors of 646 are 2 x 17 x 19

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 651, 519, 646, 406

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

Apply this formula for all numbers.

Step1:

LCM(651, 519) = 112623

GCD(651, 519) = ( 651 x 519 ) / 112623

= 651 / 519

= 651

Step2:

LCM(3, 646) = 1938

GCD(3, 646) = ( 3 x 646 ) / 1938

= 3 / 646

= 3

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 651, 519, 646, 406 is 1
