Given numbers are 170, 687, 400, 461

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 687 are 3 x 229

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 461 are 461

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

Given numbers are 170, 687, 400, 461

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

Apply this formula for all numbers.

Step1:

LCM(170, 687) = 116790

GCD(170, 687) = ( 170 x 687 ) / 116790

= 170 / 687

= 170

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

= 1 / 461

= 1

So, Greatest Common Divisor of 170, 687, 400, 461 is 1
