Given numbers are 646, 327, 280, 695

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 327 are 3 x 109

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 695 are 5 x 139

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

Given numbers are 646, 327, 280, 695

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

Apply this formula for all numbers.

Step1:

LCM(646, 327) = 211242

GCD(646, 327) = ( 646 x 327 ) / 211242

= 646 / 327

= 646

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

So, Greatest Common Divisor of 646, 327, 280, 695 is 1
