Given numbers are 646, 280, 325, 572

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

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

Prime factors of 325 are 5 x 5 x 13

Prime factors of 572 are 2 x 2 x 11 x 13

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

Given numbers are 646, 280, 325, 572

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

Apply this formula for all numbers.

Step1:

LCM(646, 280) = 90440

GCD(646, 280) = ( 646 x 280 ) / 90440

= 646 / 280

= 646

Step2:

LCM(2, 325) = 650

GCD(2, 325) = ( 2 x 325 ) / 650

= 2 / 325

= 2

Step3:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

So, Greatest Common Divisor of 646, 280, 325, 572 is 1
