Given numbers are 648, 441, 864, 259

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 259 are 7 x 37

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

Given numbers are 648, 441, 864, 259

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

Apply this formula for all numbers.

Step1:

LCM(648, 441) = 31752

GCD(648, 441) = ( 648 x 441 ) / 31752

= 648 / 441

= 648

Step2:

LCM(9, 864) = 864

GCD(9, 864) = ( 9 x 864 ) / 864

= 9 / 864

= 9

Step3:

LCM(9, 259) = 2331

GCD(9, 259) = ( 9 x 259 ) / 2331

= 9 / 259

= 9

So, Greatest Common Divisor of 648, 441, 864, 259 is 1
