Given numbers are 515, 705, 814, 408

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 705 are 3 x 5 x 47

Prime factors of 814 are 2 x 11 x 37

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 515, 705, 814, 408

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

Apply this formula for all numbers.

Step1:

LCM(515, 705) = 72615

GCD(515, 705) = ( 515 x 705 ) / 72615

= 515 / 705

= 515

Step2:

LCM(5, 814) = 4070

GCD(5, 814) = ( 5 x 814 ) / 4070

= 5 / 814

= 5

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 515, 705, 814, 408 is 1
