Given numbers are 657, 637, 389, 268
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 637) = 418509
GCD(657, 637) = ( 657 x 637 ) / 418509
= 657 / 637
= 657
Step2:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
Step3:
LCM(1, 268) = 268
GCD(1, 268) = ( 1 x 268 ) / 268
= 1 / 268
= 1
So, Greatest Common Divisor of 657, 637, 389, 268 is 1
