GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(994, 108) = 53676
GCD(994, 108) = ( 994 x 108 ) / 53676
= 994 / 108
= 994
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
So, Greatest Common Divisor of 994, 108, 646, 391 is 1
