Given numbers are 408, 138, 252, 503

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 138 are 2 x 3 x 23

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 503 are 503

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

Given numbers are 408, 138, 252, 503

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

Apply this formula for all numbers.

Step1:

LCM(408, 138) = 9384

GCD(408, 138) = ( 408 x 138 ) / 9384

= 408 / 138

= 408

Step2:

LCM(6, 252) = 252

GCD(6, 252) = ( 6 x 252 ) / 252

= 6 / 252

= 6

Step3:

LCM(6, 503) = 3018

GCD(6, 503) = ( 6 x 503 ) / 3018

= 6 / 503

= 6

So, Greatest Common Divisor of 408, 138, 252, 503 is 1
