Given numbers are 780, 317, 870, 413

The list of prime factors of all numbers are

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

Prime factors of 317 are 317

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 413 are 7 x 59

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

Given numbers are 780, 317, 870, 413

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

Apply this formula for all numbers.

Step1:

LCM(780, 317) = 247260

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

= 780 / 317

= 780

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 780, 317, 870, 413 is 1
