Given numbers are 403, 520, 270, 249

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 249 are 3 x 83

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

Given numbers are 403, 520, 270, 249

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

Apply this formula for all numbers.

Step1:

LCM(403, 520) = 16120

GCD(403, 520) = ( 403 x 520 ) / 16120

= 403 / 520

= 403

Step2:

LCM(13, 270) = 3510

GCD(13, 270) = ( 13 x 270 ) / 3510

= 13 / 270

= 13

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 403, 520, 270, 249 is 1
