Given numbers are 686, 315, 959, 745

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

Apply this formula for all numbers.

Step1:

LCM(686, 315) = 30870

GCD(686, 315) = ( 686 x 315 ) / 30870

= 686 / 315

= 686

Step2:

LCM(7, 959) = 959

GCD(7, 959) = ( 7 x 959 ) / 959

= 7 / 959

= 7

Step3:

LCM(7, 745) = 5215

GCD(7, 745) = ( 7 x 745 ) / 5215

= 7 / 745

= 7

So, Greatest Common Divisor of 686, 315, 959, 745 is 1
