Given numbers are 878, 173, 860, 855

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 173 are 173

Prime factors of 860 are 2 x 2 x 5 x 43

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

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

Given numbers are 878, 173, 860, 855

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

Apply this formula for all numbers.

Step1:

LCM(878, 173) = 151894

GCD(878, 173) = ( 878 x 173 ) / 151894

= 878 / 173

= 878

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 878, 173, 860, 855 is 1
