Given numbers are 317, 780, 462, 261

The list of prime factors of all numbers are

Prime factors of 317 are 317

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

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 317, 780, 462, 261

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

Apply this formula for all numbers.

Step1:

LCM(317, 780) = 247260

GCD(317, 780) = ( 317 x 780 ) / 247260

= 317 / 780

= 317

Step2:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 317, 780, 462, 261 is 1
