GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 660) = 11220
GCD(748, 660) = ( 748 x 660 ) / 11220
= 748 / 660
= 748
Step2:
LCM(44, 774) = 17028
GCD(44, 774) = ( 44 x 774 ) / 17028
= 44 / 774
= 44
Step3:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
So, Greatest Common Divisor of 748, 660, 774, 556 is 2
