Given numbers are 103, 257, 936, 420

The list of prime factors of all numbers are

Prime factors of 103 are 103

Prime factors of 257 are 257

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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 103, 257, 936, 420

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

Apply this formula for all numbers.

Step1:

LCM(103, 257) = 26471

GCD(103, 257) = ( 103 x 257 ) / 26471

= 103 / 257

= 103

Step2:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 103, 257, 936, 420 is 1
