The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 123, 113, 449, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 113) = 13899
GCD(123, 113) = ( 123 x 113 ) / 13899
= 123 / 113
= 123
Step2:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 123, 113, 449, 640 is 1
