The list of prime factors of all numbers are

Prime factors of 839 are 839

Prime factors of 170 are 2 x 5 x 17

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 839, 170, 688, 450

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

Apply this formula for all numbers.

Step1:

LCM(839, 170) = 142630

GCD(839, 170) = ( 839 x 170 ) / 142630

= 839 / 170

= 839

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 839, 170, 688, 450 is 1
