Given numbers are 355, 149, 279, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 149) = 52895
GCD(355, 149) = ( 355 x 149 ) / 52895
= 355 / 149
= 355
Step2:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 355, 149, 279, 129 is 1
