Given numbers are 990, 771, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 771) = 254430
GCD(990, 771) = ( 990 x 771 ) / 254430
= 990 / 771
= 990
Step2:
LCM(3, 392) = 1176
GCD(3, 392) = ( 3 x 392 ) / 1176
= 3 / 392
= 3
So, Greatest Common Divisor of 990, 771, 392 is 1
