Given numbers are 861, 318, 130, 550

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 318 are 2 x 3 x 53

Prime factors of 130 are 2 x 5 x 13

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 861, 318, 130, 550

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

Apply this formula for all numbers.

Step1:

LCM(861, 318) = 91266

GCD(861, 318) = ( 861 x 318 ) / 91266

= 861 / 318

= 861

Step2:

LCM(3, 130) = 390

GCD(3, 130) = ( 3 x 130 ) / 390

= 3 / 130

= 3

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 861, 318, 130, 550 is 1
