Given numbers are 861, 312, 255, 725

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 255 are 3 x 5 x 17

Prime factors of 725 are 5 x 5 x 29

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

Given numbers are 861, 312, 255, 725

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

Apply this formula for all numbers.

Step1:

LCM(861, 312) = 89544

GCD(861, 312) = ( 861 x 312 ) / 89544

= 861 / 312

= 861

Step2:

LCM(3, 255) = 255

GCD(3, 255) = ( 3 x 255 ) / 255

= 3 / 255

= 3

Step3:

LCM(3, 725) = 2175

GCD(3, 725) = ( 3 x 725 ) / 2175

= 3 / 725

= 3

So, Greatest Common Divisor of 861, 312, 255, 725 is 1
