Given numbers are 415, 824, 406, 520

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 406 are 2 x 7 x 29

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 415, 824, 406, 520

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

Apply this formula for all numbers.

Step1:

LCM(415, 824) = 341960

GCD(415, 824) = ( 415 x 824 ) / 341960

= 415 / 824

= 415

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 415, 824, 406, 520 is 1
