GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(682, 840) = 286440
GCD(682, 840) = ( 682 x 840 ) / 286440
= 682 / 840
= 682
Step2:
LCM(2, 968) = 968
GCD(2, 968) = ( 2 x 968 ) / 968
= 2 / 968
= 2
Step3:
LCM(2, 458) = 458
GCD(2, 458) = ( 2 x 458 ) / 458
= 2 / 458
= 2
So, Greatest Common Divisor of 682, 840, 968, 458 is 2
