Given numbers are 656, 604, 775, 280

The list of prime factors of all numbers are

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 604 are 2 x 2 x 151

Prime factors of 775 are 5 x 5 x 31

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

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

Given numbers are 656, 604, 775, 280

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

Apply this formula for all numbers.

Step1:

LCM(656, 604) = 99056

GCD(656, 604) = ( 656 x 604 ) / 99056

= 656 / 604

= 656

Step2:

LCM(4, 775) = 3100

GCD(4, 775) = ( 4 x 775 ) / 3100

= 4 / 775

= 4

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 656, 604, 775, 280 is 1
