Given numbers are 505, 418, 520, 210

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 418 are 2 x 11 x 19

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

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 505, 418, 520, 210

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

Apply this formula for all numbers.

Step1:

LCM(505, 418) = 211090

GCD(505, 418) = ( 505 x 418 ) / 211090

= 505 / 418

= 505

Step2:

LCM(1, 520) = 520

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

= 1 / 520

= 1

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 505, 418, 520, 210 is 1
