Given numbers are 399, 310, 553, 538

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 310 are 2 x 5 x 31

Prime factors of 553 are 7 x 79

Prime factors of 538 are 2 x 269

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

Given numbers are 399, 310, 553, 538

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

Apply this formula for all numbers.

Step1:

LCM(399, 310) = 123690

GCD(399, 310) = ( 399 x 310 ) / 123690

= 399 / 310

= 399

Step2:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 399, 310, 553, 538 is 1
