Given numbers are 347, 408, 770, 855

The list of prime factors of all numbers are

Prime factors of 347 are 347

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 770 are 2 x 5 x 7 x 11

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 347, 408, 770, 855

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

Apply this formula for all numbers.

Step1:

LCM(347, 408) = 141576

GCD(347, 408) = ( 347 x 408 ) / 141576

= 347 / 408

= 347

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 855) = 855

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

= 1 / 855

= 1

So, Greatest Common Divisor of 347, 408, 770, 855 is 1
