Given numbers are 403, 161, 298, 418

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 161 are 7 x 23

Prime factors of 298 are 2 x 149

Prime factors of 418 are 2 x 11 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 403, 161, 298, 418

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(403, 161) = 64883

GCD(403, 161) = ( 403 x 161 ) / 64883

= 403 / 161

= 403

Step2:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 403, 161, 298, 418 is 1
