GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 657) = 201699
GCD(921, 657) = ( 921 x 657 ) / 201699
= 921 / 657
= 921
Step2:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 921, 657, 439, 891 is 1
