Given numbers are 253, 815, 607, 408

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 815 are 5 x 163

Prime factors of 607 are 607

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 253, 815, 607, 408

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

Apply this formula for all numbers.

Step1:

LCM(253, 815) = 206195

GCD(253, 815) = ( 253 x 815 ) / 206195

= 253 / 815

= 253

Step2:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

Step3:

LCM(1, 408) = 408

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

= 1 / 408

= 1

So, Greatest Common Divisor of 253, 815, 607, 408 is 1
