GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 928) = 173536
GCD(748, 928) = ( 748 x 928 ) / 173536
= 748 / 928
= 748
Step2:
LCM(4, 261) = 1044
GCD(4, 261) = ( 4 x 261 ) / 1044
= 4 / 261
= 4
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 748, 928, 261, 646 is 1
