GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(204, 646) = 3876
GCD(204, 646) = ( 204 x 646 ) / 3876
= 204 / 646
= 204
Step2:
LCM(34, 637) = 21658
GCD(34, 637) = ( 34 x 637 ) / 21658
= 34 / 637
= 34
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 204, 646, 637, 649 is 1
