Given numbers are 603, 903, 42, 254

The list of prime factors of all numbers are

Prime factors of 603 are 3 x 3 x 67

Prime factors of 903 are 3 x 7 x 43

Prime factors of 42 are 2 x 3 x 7

Prime factors of 254 are 2 x 127

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

Given numbers are 603, 903, 42, 254

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

Apply this formula for all numbers.

Step1:

LCM(603, 903) = 181503

GCD(603, 903) = ( 603 x 903 ) / 181503

= 603 / 903

= 603

Step2:

LCM(3, 42) = 42

GCD(3, 42) = ( 3 x 42 ) / 42

= 3 / 42

= 3

Step3:

LCM(3, 254) = 762

GCD(3, 254) = ( 3 x 254 ) / 762

= 3 / 254

= 3

So, Greatest Common Divisor of 603, 903, 42, 254 is 1
