GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 634) = 211756
GCD(668, 634) = ( 668 x 634 ) / 211756
= 668 / 634
= 668
Step2:
LCM(2, 411) = 822
GCD(2, 411) = ( 2 x 411 ) / 822
= 2 / 411
= 2
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 668, 634, 411, 977 is 1
