Given numbers are 403, 513, 727, 780

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 727 are 727

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 403, 513, 727, 780

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

Apply this formula for all numbers.

Step1:

LCM(403, 513) = 206739

GCD(403, 513) = ( 403 x 513 ) / 206739

= 403 / 513

= 403

Step2:

LCM(1, 727) = 727

GCD(1, 727) = ( 1 x 727 ) / 727

= 1 / 727

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 403, 513, 727, 780 is 1
