Given numbers are 247, 618, 168, 170

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 618 are 2 x 3 x 103

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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 247, 618, 168, 170

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

Apply this formula for all numbers.

Step1:

LCM(247, 618) = 152646

GCD(247, 618) = ( 247 x 618 ) / 152646

= 247 / 618

= 247

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 170) = 170

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

= 1 / 170

= 1

So, Greatest Common Divisor of 247, 618, 168, 170 is 1
