Given numbers are 170, 751, 639, 351

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 751 are 751

Prime factors of 639 are 3 x 3 x 71

Prime factors of 351 are 3 x 3 x 3 x 13

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

Given numbers are 170, 751, 639, 351

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

Apply this formula for all numbers.

Step1:

LCM(170, 751) = 127670

GCD(170, 751) = ( 170 x 751 ) / 127670

= 170 / 751

= 170

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 170, 751, 639, 351 is 1
