GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 108) = 34884
GCD(646, 108) = ( 646 x 108 ) / 34884
= 646 / 108
= 646
Step2:
LCM(2, 379) = 758
GCD(2, 379) = ( 2 x 379 ) / 758
= 2 / 379
= 2
Step3:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
So, Greatest Common Divisor of 646, 108, 379, 816 is 1
