Given numbers are 686, 198, 717, 957

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

Apply this formula for all numbers.

Step1:

LCM(686, 198) = 67914

GCD(686, 198) = ( 686 x 198 ) / 67914

= 686 / 198

= 686

Step2:

LCM(2, 717) = 1434

GCD(2, 717) = ( 2 x 717 ) / 1434

= 2 / 717

= 2

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 686, 198, 717, 957 is 1
