Given numbers are 861, 505, 286, 395

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 505 are 5 x 101

Prime factors of 286 are 2 x 11 x 13

Prime factors of 395 are 5 x 79

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

Given numbers are 861, 505, 286, 395

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

Apply this formula for all numbers.

Step1:

LCM(861, 505) = 434805

GCD(861, 505) = ( 861 x 505 ) / 434805

= 861 / 505

= 861

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 861, 505, 286, 395 is 1
