Given numbers are 170, 309, 407, 970

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 309 are 3 x 103

Prime factors of 407 are 11 x 37

Prime factors of 970 are 2 x 5 x 97

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

Given numbers are 170, 309, 407, 970

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

Apply this formula for all numbers.

Step1:

LCM(170, 309) = 52530

GCD(170, 309) = ( 170 x 309 ) / 52530

= 170 / 309

= 170

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 170, 309, 407, 970 is 1
