Given numbers are 105, 346, 215, 855

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 346 are 2 x 173

Prime factors of 215 are 5 x 43

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 105, 346, 215, 855

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

Apply this formula for all numbers.

Step1:

LCM(105, 346) = 36330

GCD(105, 346) = ( 105 x 346 ) / 36330

= 105 / 346

= 105

Step2:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 105, 346, 215, 855 is 1
