Given numbers are 875, 619, 780, 865

The list of prime factors of all numbers are

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 619 are 619

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

Prime factors of 865 are 5 x 173

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

Given numbers are 875, 619, 780, 865

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

Apply this formula for all numbers.

Step1:

LCM(875, 619) = 541625

GCD(875, 619) = ( 875 x 619 ) / 541625

= 875 / 619

= 875

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 875, 619, 780, 865 is 1
