Given numbers are 280, 404, 721, 630

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 404 are 2 x 2 x 101

Prime factors of 721 are 7 x 103

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 280, 404, 721, 630

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

Apply this formula for all numbers.

Step1:

LCM(280, 404) = 28280

GCD(280, 404) = ( 280 x 404 ) / 28280

= 280 / 404

= 280

Step2:

LCM(4, 721) = 2884

GCD(4, 721) = ( 4 x 721 ) / 2884

= 4 / 721

= 4

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 280, 404, 721, 630 is 1
