Given numbers are 149, 137, 742, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(149, 137) = 20413
GCD(149, 137) = ( 149 x 137 ) / 20413
= 149 / 137
= 149
Step2:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 149, 137, 742, 394 is 1
