GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 638) = 248182
GCD(778, 638) = ( 778 x 638 ) / 248182
= 778 / 638
= 778
Step2:
LCM(2, 920) = 920
GCD(2, 920) = ( 2 x 920 ) / 920
= 2 / 920
= 2
Step3:
LCM(2, 750) = 750
GCD(2, 750) = ( 2 x 750 ) / 750
= 2 / 750
= 2
So, Greatest Common Divisor of 778, 638, 920, 750 is 2
