Given numbers are 727, 515, 556, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(727, 515) = 374405
GCD(727, 515) = ( 727 x 515 ) / 374405
= 727 / 515
= 727
Step2:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 727, 515, 556, 921 is 1
