Given numbers are 305, 486, 421, 384

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 421 are 421

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 305, 486, 421, 384

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

Apply this formula for all numbers.

Step1:

LCM(305, 486) = 148230

GCD(305, 486) = ( 305 x 486 ) / 148230

= 305 / 486

= 305

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 305, 486, 421, 384 is 1
