GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 418) = 164692
GCD(788, 418) = ( 788 x 418 ) / 164692
= 788 / 418
= 788
Step2:
LCM(2, 256) = 256
GCD(2, 256) = ( 2 x 256 ) / 256
= 2 / 256
= 2
Step3:
LCM(2, 280) = 280
GCD(2, 280) = ( 2 x 280 ) / 280
= 2 / 280
= 2
So, Greatest Common Divisor of 788, 418, 256, 280 is 2
