Given numbers are 695, 407, 170, 189

The list of prime factors of all numbers are

Prime factors of 695 are 5 x 139

Prime factors of 407 are 11 x 37

Prime factors of 170 are 2 x 5 x 17

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 695, 407, 170, 189

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

Apply this formula for all numbers.

Step1:

LCM(695, 407) = 282865

GCD(695, 407) = ( 695 x 407 ) / 282865

= 695 / 407

= 695

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 695, 407, 170, 189 is 1
