GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 130) = 51220
GCD(788, 130) = ( 788 x 130 ) / 51220
= 788 / 130
= 788
Step2:
LCM(2, 446) = 446
GCD(2, 446) = ( 2 x 446 ) / 446
= 2 / 446
= 2
Step3:
LCM(2, 392) = 392
GCD(2, 392) = ( 2 x 392 ) / 392
= 2 / 392
= 2
So, Greatest Common Divisor of 788, 130, 446, 392 is 2
