Given numbers are 680, 740, 720, 239

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 740 are 2 x 2 x 5 x 37

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 239 are 239

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

Given numbers are 680, 740, 720, 239

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

Apply this formula for all numbers.

Step1:

LCM(680, 740) = 25160

GCD(680, 740) = ( 680 x 740 ) / 25160

= 680 / 740

= 680

Step2:

LCM(20, 720) = 720

GCD(20, 720) = ( 20 x 720 ) / 720

= 20 / 720

= 20

Step3:

LCM(20, 239) = 4780

GCD(20, 239) = ( 20 x 239 ) / 4780

= 20 / 239

= 20

So, Greatest Common Divisor of 680, 740, 720, 239 is 1
