Given numbers are 478, 253, 447, 305

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 253 are 11 x 23

Prime factors of 447 are 3 x 149

Prime factors of 305 are 5 x 61

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

Given numbers are 478, 253, 447, 305

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

Apply this formula for all numbers.

Step1:

LCM(478, 253) = 120934

GCD(478, 253) = ( 478 x 253 ) / 120934

= 478 / 253

= 478

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 478, 253, 447, 305 is 1
