Given numbers are 680, 168, 745, 144

The list of prime factors of all numbers are

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

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

Prime factors of 745 are 5 x 149

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 680, 168, 745, 144

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

Apply this formula for all numbers.

Step1:

LCM(680, 168) = 14280

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

= 680 / 168

= 680

Step2:

LCM(8, 745) = 5960

GCD(8, 745) = ( 8 x 745 ) / 5960

= 8 / 745

= 8

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 680, 168, 745, 144 is 1
