Given numbers are 711, 656, 780, 311

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

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 311 are 311

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

Given numbers are 711, 656, 780, 311

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

Apply this formula for all numbers.

Step1:

LCM(711, 656) = 466416

GCD(711, 656) = ( 711 x 656 ) / 466416

= 711 / 656

= 711

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 711, 656, 780, 311 is 1
