Given numbers are 403, 663, 309, 540

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 663 are 3 x 13 x 17

Prime factors of 309 are 3 x 103

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 403, 663, 309, 540

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

Apply this formula for all numbers.

Step1:

LCM(403, 663) = 20553

GCD(403, 663) = ( 403 x 663 ) / 20553

= 403 / 663

= 403

Step2:

LCM(13, 309) = 4017

GCD(13, 309) = ( 13 x 309 ) / 4017

= 13 / 309

= 13

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 403, 663, 309, 540 is 1
