Given numbers are 206, 954, 855, 857

The list of prime factors of all numbers are

Prime factors of 206 are 2 x 103

Prime factors of 954 are 2 x 3 x 3 x 53

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

Prime factors of 857 are 857

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

Given numbers are 206, 954, 855, 857

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

Apply this formula for all numbers.

Step1:

LCM(206, 954) = 98262

GCD(206, 954) = ( 206 x 954 ) / 98262

= 206 / 954

= 206

Step2:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 206, 954, 855, 857 is 1
