Given numbers are 921, 645, 556, 583
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 645) = 198015
GCD(921, 645) = ( 921 x 645 ) / 198015
= 921 / 645
= 921
Step2:
LCM(3, 556) = 1668
GCD(3, 556) = ( 3 x 556 ) / 1668
= 3 / 556
= 3
Step3:
LCM(1, 583) = 583
GCD(1, 583) = ( 1 x 583 ) / 583
= 1 / 583
= 1
So, Greatest Common Divisor of 921, 645, 556, 583 is 1
