GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 312) = 5304
GCD(663, 312) = ( 663 x 312 ) / 5304
= 663 / 312
= 663
Step2:
LCM(39, 921) = 11973
GCD(39, 921) = ( 39 x 921 ) / 11973
= 39 / 921
= 39
Step3:
LCM(3, 277) = 831
GCD(3, 277) = ( 3 x 277 ) / 831
= 3 / 277
= 3
So, Greatest Common Divisor of 663, 312, 921, 277 is 1
