Given numbers are 657, 608, 646, 103
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 608) = 399456
GCD(657, 608) = ( 657 x 608 ) / 399456
= 657 / 608
= 657
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 103) = 103
GCD(1, 103) = ( 1 x 103 ) / 103
= 1 / 103
= 1
So, Greatest Common Divisor of 657, 608, 646, 103 is 1
