Given numbers are 247, 635, 720, 223

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 635 are 5 x 127

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

Prime factors of 223 are 223

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

Given numbers are 247, 635, 720, 223

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

Apply this formula for all numbers.

Step1:

LCM(247, 635) = 156845

GCD(247, 635) = ( 247 x 635 ) / 156845

= 247 / 635

= 247

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 247, 635, 720, 223 is 1
