Given numbers are 605, 121, 520, 510

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 121 are 11 x 11

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

Prime factors of 510 are 2 x 3 x 5 x 17

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

Given numbers are 605, 121, 520, 510

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

Apply this formula for all numbers.

Step1:

LCM(605, 121) = 605

GCD(605, 121) = ( 605 x 121 ) / 605

= 605 / 121

= 605

Step2:

LCM(121, 520) = 62920

GCD(121, 520) = ( 121 x 520 ) / 62920

= 121 / 520

= 121

Step3:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

So, Greatest Common Divisor of 605, 121, 520, 510 is 1
