GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 118) = 7434
GCD(126, 118) = ( 126 x 118 ) / 7434
= 126 / 118
= 126
Step2:
LCM(2, 748) = 748
GCD(2, 748) = ( 2 x 748 ) / 748
= 2 / 748
= 2
Step3:
LCM(2, 128) = 128
GCD(2, 128) = ( 2 x 128 ) / 128
= 2 / 128
= 2
So, Greatest Common Divisor of 126, 118, 748, 128 is 2
