GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 494) = 334438
GCD(677, 494) = ( 677 x 494 ) / 334438
= 677 / 494
= 677
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
So, Greatest Common Divisor of 677, 494, 405, 939 is 1
