Given numbers are 517, 245, 63, 864

The list of prime factors of all numbers are

Prime factors of 517 are 11 x 47

Prime factors of 245 are 5 x 7 x 7

Prime factors of 63 are 3 x 3 x 7

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

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

Given numbers are 517, 245, 63, 864

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

Apply this formula for all numbers.

Step1:

LCM(517, 245) = 126665

GCD(517, 245) = ( 517 x 245 ) / 126665

= 517 / 245

= 517

Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 517, 245, 63, 864 is 1
