Given numbers are 310, 668, 656, 405

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 668 are 2 x 2 x 167

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

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 310, 668, 656, 405

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

Apply this formula for all numbers.

Step1:

LCM(310, 668) = 103540

GCD(310, 668) = ( 310 x 668 ) / 103540

= 310 / 668

= 310

Step2:

LCM(2, 656) = 656

GCD(2, 656) = ( 2 x 656 ) / 656

= 2 / 656

= 2

Step3:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

So, Greatest Common Divisor of 310, 668, 656, 405 is 1
