GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 180) = 14220
GCD(790, 180) = ( 790 x 180 ) / 14220
= 790 / 180
= 790
Step2:
LCM(10, 348) = 1740
GCD(10, 348) = ( 10 x 348 ) / 1740
= 10 / 348
= 10
Step3:
LCM(2, 656) = 656
GCD(2, 656) = ( 2 x 656 ) / 656
= 2 / 656
= 2
So, Greatest Common Divisor of 790, 180, 348, 656 is 2
