Given numbers are 680, 720, 247, 881

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 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 247 are 13 x 19

Prime factors of 881 are 881

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

Given numbers are 680, 720, 247, 881

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

Apply this formula for all numbers.

Step1:

LCM(680, 720) = 12240

GCD(680, 720) = ( 680 x 720 ) / 12240

= 680 / 720

= 680

Step2:

LCM(40, 247) = 9880

GCD(40, 247) = ( 40 x 247 ) / 9880

= 40 / 247

= 40

Step3:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

So, Greatest Common Divisor of 680, 720, 247, 881 is 1
