Given numbers are 168, 680, 490, 675

The list of prime factors of all numbers are

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

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 675 are 3 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 168, 680, 490, 675

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

Apply this formula for all numbers.

Step1:

LCM(168, 680) = 14280

GCD(168, 680) = ( 168 x 680 ) / 14280

= 168 / 680

= 168

Step2:

LCM(8, 490) = 1960

GCD(8, 490) = ( 8 x 490 ) / 1960

= 8 / 490

= 8

Step3:

LCM(2, 675) = 1350

GCD(2, 675) = ( 2 x 675 ) / 1350

= 2 / 675

= 2

So, Greatest Common Divisor of 168, 680, 490, 675 is 1
