Given numbers are 245, 115, 234, 520

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 115 are 5 x 23

Prime factors of 234 are 2 x 3 x 3 x 13

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 245, 115, 234, 520

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

Apply this formula for all numbers.

Step1:

LCM(245, 115) = 5635

GCD(245, 115) = ( 245 x 115 ) / 5635

= 245 / 115

= 245

Step2:

LCM(5, 234) = 1170

GCD(5, 234) = ( 5 x 234 ) / 1170

= 5 / 234

= 5

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 245, 115, 234, 520 is 1
