GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 939) = 627252
GCD(668, 939) = ( 668 x 939 ) / 627252
= 668 / 939
= 668
Step2:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
Step3:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
So, Greatest Common Divisor of 668, 939, 808, 931 is 1
