Given numbers are 961, 561, 688, 608

The list of prime factors of all numbers are

Prime factors of 961 are 31 x 31

Prime factors of 561 are 3 x 11 x 17

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

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

Given numbers are 961, 561, 688, 608

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

Apply this formula for all numbers.

Step1:

LCM(961, 561) = 539121

GCD(961, 561) = ( 961 x 561 ) / 539121

= 961 / 561

= 961

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 608) = 608

GCD(1, 608) = ( 1 x 608 ) / 608

= 1 / 608

= 1

So, Greatest Common Divisor of 961, 561, 688, 608 is 1
