GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(994, 420) = 29820
GCD(994, 420) = ( 994 x 420 ) / 29820
= 994 / 420
= 994
Step2:
LCM(14, 831) = 11634
GCD(14, 831) = ( 14 x 831 ) / 11634
= 14 / 831
= 14
So, Greatest Common Divisor of 994, 420, 831 is 1
