Given numbers are 247, 273, 644, 260

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 273 are 3 x 7 x 13

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 260 are 2 x 2 x 5 x 13

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

Given numbers are 247, 273, 644, 260

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

Apply this formula for all numbers.

Step1:

LCM(247, 273) = 5187

GCD(247, 273) = ( 247 x 273 ) / 5187

= 247 / 273

= 247

Step2:

LCM(13, 644) = 8372

GCD(13, 644) = ( 13 x 644 ) / 8372

= 13 / 644

= 13

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 247, 273, 644, 260 is 1
