Given numbers are 638, 323, 309, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 323) = 206074
GCD(638, 323) = ( 638 x 323 ) / 206074
= 638 / 323
= 638
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 638, 323, 309, 406 is 1
