Given numbers are 847, 170, 728, 306

The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 170 are 2 x 5 x 17

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 847, 170, 728, 306

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

Apply this formula for all numbers.

Step1:

LCM(847, 170) = 143990

GCD(847, 170) = ( 847 x 170 ) / 143990

= 847 / 170

= 847

Step2:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 847, 170, 728, 306 is 1
