Given numbers are 861, 247, 320, 250

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 247 are 13 x 19

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 250 are 2 x 5 x 5 x 5

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

Given numbers are 861, 247, 320, 250

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

Apply this formula for all numbers.

Step1:

LCM(861, 247) = 212667

GCD(861, 247) = ( 861 x 247 ) / 212667

= 861 / 247

= 861

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 861, 247, 320, 250 is 1
