Given numbers are 815, 515, 520, 414

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 515 are 5 x 103

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

Prime factors of 414 are 2 x 3 x 3 x 23

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

Given numbers are 815, 515, 520, 414

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

Apply this formula for all numbers.

Step1:

LCM(815, 515) = 83945

GCD(815, 515) = ( 815 x 515 ) / 83945

= 815 / 515

= 815

Step2:

LCM(5, 520) = 520

GCD(5, 520) = ( 5 x 520 ) / 520

= 5 / 520

= 5

Step3:

LCM(5, 414) = 2070

GCD(5, 414) = ( 5 x 414 ) / 2070

= 5 / 414

= 5

So, Greatest Common Divisor of 815, 515, 520, 414 is 1
