Given numbers are 418, 449, 357, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(418, 449) = 187682
GCD(418, 449) = ( 418 x 449 ) / 187682
= 418 / 449
= 418
Step2:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 418, 449, 357, 163 is 1
