Given numbers are 756, 855, 520, 878

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 878 are 2 x 439

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

Given numbers are 756, 855, 520, 878

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

Apply this formula for all numbers.

Step1:

LCM(756, 855) = 71820

GCD(756, 855) = ( 756 x 855 ) / 71820

= 756 / 855

= 756

Step2:

LCM(9, 520) = 4680

GCD(9, 520) = ( 9 x 520 ) / 4680

= 9 / 520

= 9

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 756, 855, 520, 878 is 1
