Given numbers are 957, 345, 917, 688

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

Apply this formula for all numbers.

Step1:

LCM(957, 345) = 110055

GCD(957, 345) = ( 957 x 345 ) / 110055

= 957 / 345

= 957

Step2:

LCM(3, 917) = 2751

GCD(3, 917) = ( 3 x 917 ) / 2751

= 3 / 917

= 3

Step3:

LCM(1, 688) = 688

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

= 1 / 688

= 1

So, Greatest Common Divisor of 957, 345, 917, 688 is 1
