Given numbers are 399, 369, 418, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 369) = 49077
GCD(399, 369) = ( 399 x 369 ) / 49077
= 399 / 369
= 399
Step2:
LCM(3, 418) = 1254
GCD(3, 418) = ( 3 x 418 ) / 1254
= 3 / 418
= 3
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 399, 369, 418, 161 is 1
