Given numbers are 865, 270, 789, 251

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 789 are 3 x 263

Prime factors of 251 are 251

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

Given numbers are 865, 270, 789, 251

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

Apply this formula for all numbers.

Step1:

LCM(865, 270) = 46710

GCD(865, 270) = ( 865 x 270 ) / 46710

= 865 / 270

= 865

Step2:

LCM(5, 789) = 3945

GCD(5, 789) = ( 5 x 789 ) / 3945

= 5 / 789

= 5

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 865, 270, 789, 251 is 1
