GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(136, 561) = 4488
GCD(136, 561) = ( 136 x 561 ) / 4488
= 136 / 561
= 136
Step2:
LCM(17, 928) = 15776
GCD(17, 928) = ( 17 x 928 ) / 15776
= 17 / 928
= 17
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 136, 561, 928, 728 is 1
