Given numbers are 345, 561, 656, 461

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 561 are 3 x 11 x 17

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

Prime factors of 461 are 461

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

Given numbers are 345, 561, 656, 461

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

Apply this formula for all numbers.

Step1:

LCM(345, 561) = 64515

GCD(345, 561) = ( 345 x 561 ) / 64515

= 345 / 561

= 345

Step2:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

Step3:

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

= 1 / 461

= 1

So, Greatest Common Divisor of 345, 561, 656, 461 is 1
