Given numbers are 455, 515, 175, 408

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 515 are 5 x 103

Prime factors of 175 are 5 x 5 x 7

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 455, 515, 175, 408

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

Apply this formula for all numbers.

Step1:

LCM(455, 515) = 46865

GCD(455, 515) = ( 455 x 515 ) / 46865

= 455 / 515

= 455

Step2:

LCM(5, 175) = 175

GCD(5, 175) = ( 5 x 175 ) / 175

= 5 / 175

= 5

Step3:

LCM(5, 408) = 2040

GCD(5, 408) = ( 5 x 408 ) / 2040

= 5 / 408

= 5

So, Greatest Common Divisor of 455, 515, 175, 408 is 1
