Given numbers are 280, 605, 224, 680

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 605 are 5 x 11 x 11

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

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

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

Given numbers are 280, 605, 224, 680

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

Apply this formula for all numbers.

Step1:

LCM(280, 605) = 33880

GCD(280, 605) = ( 280 x 605 ) / 33880

= 280 / 605

= 280

Step2:

LCM(5, 224) = 1120

GCD(5, 224) = ( 5 x 224 ) / 1120

= 5 / 224

= 5

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 280, 605, 224, 680 is 1
