Given numbers are 687, 770, 822, 170

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 822 are 2 x 3 x 137

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 687, 770, 822, 170

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

Apply this formula for all numbers.

Step1:

LCM(687, 770) = 528990

GCD(687, 770) = ( 687 x 770 ) / 528990

= 687 / 770

= 687

Step2:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

Step3:

LCM(1, 170) = 170

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

= 1 / 170

= 1

So, Greatest Common Divisor of 687, 770, 822, 170 is 1
