Given numbers are 342, 855, 447, 290

The list of prime factors of all numbers are

Prime factors of 342 are 2 x 3 x 3 x 19

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

Prime factors of 447 are 3 x 149

Prime factors of 290 are 2 x 5 x 29

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

Given numbers are 342, 855, 447, 290

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

Apply this formula for all numbers.

Step1:

LCM(342, 855) = 1710

GCD(342, 855) = ( 342 x 855 ) / 1710

= 342 / 855

= 342

Step2:

LCM(171, 447) = 25479

GCD(171, 447) = ( 171 x 447 ) / 25479

= 171 / 447

= 171

Step3:

LCM(3, 290) = 870

GCD(3, 290) = ( 3 x 290 ) / 870

= 3 / 290

= 3

So, Greatest Common Divisor of 342, 855, 447, 290 is 1
