Given numbers are 520, 245, 255, 506

The list of prime factors of all numbers are

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

Prime factors of 245 are 5 x 7 x 7

Prime factors of 255 are 3 x 5 x 17

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 520, 245, 255, 506

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

Apply this formula for all numbers.

Step1:

LCM(520, 245) = 25480

GCD(520, 245) = ( 520 x 245 ) / 25480

= 520 / 245

= 520

Step2:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

Step3:

LCM(5, 506) = 2530

GCD(5, 506) = ( 5 x 506 ) / 2530

= 5 / 506

= 5

So, Greatest Common Divisor of 520, 245, 255, 506 is 1
