Given numbers are 322, 656, 780, 231

The list of prime factors of all numbers are

Prime factors of 322 are 2 x 7 x 23

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 322, 656, 780, 231

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

Apply this formula for all numbers.

Step1:

LCM(322, 656) = 105616

GCD(322, 656) = ( 322 x 656 ) / 105616

= 322 / 656

= 322

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 231) = 462

GCD(2, 231) = ( 2 x 231 ) / 462

= 2 / 231

= 2

So, Greatest Common Divisor of 322, 656, 780, 231 is 1
