Given numbers are 346, 284, 440, 861

The list of prime factors of all numbers are

Prime factors of 346 are 2 x 173

Prime factors of 284 are 2 x 2 x 71

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 346, 284, 440, 861

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

Apply this formula for all numbers.

Step1:

LCM(346, 284) = 49132

GCD(346, 284) = ( 346 x 284 ) / 49132

= 346 / 284

= 346

Step2:

LCM(2, 440) = 440

GCD(2, 440) = ( 2 x 440 ) / 440

= 2 / 440

= 2

Step3:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

So, Greatest Common Divisor of 346, 284, 440, 861 is 1
