Given numbers are 386, 604, 253, 420

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 604 are 2 x 2 x 151

Prime factors of 253 are 11 x 23

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 386, 604, 253, 420

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

Apply this formula for all numbers.

Step1:

LCM(386, 604) = 116572

GCD(386, 604) = ( 386 x 604 ) / 116572

= 386 / 604

= 386

Step2:

LCM(2, 253) = 506

GCD(2, 253) = ( 2 x 253 ) / 506

= 2 / 253

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 386, 604, 253, 420 is 1
