Given numbers are 665, 538, 480, 311

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 538 are 2 x 269

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 311 are 311

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

Given numbers are 665, 538, 480, 311

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

Apply this formula for all numbers.

Step1:

LCM(665, 538) = 357770

GCD(665, 538) = ( 665 x 538 ) / 357770

= 665 / 538

= 665

Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 665, 538, 480, 311 is 1
