GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 352) = 120736
GCD(686, 352) = ( 686 x 352 ) / 120736
= 686 / 352
= 686
Step2:
LCM(2, 121) = 242
GCD(2, 121) = ( 2 x 121 ) / 242
= 2 / 121
= 2
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 686, 352, 121, 956 is 1
