Given numbers are 490, 428, 855, 303

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 428 are 2 x 2 x 107

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 303 are 3 x 101

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

Given numbers are 490, 428, 855, 303

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

Apply this formula for all numbers.

Step1:

LCM(490, 428) = 104860

GCD(490, 428) = ( 490 x 428 ) / 104860

= 490 / 428

= 490

Step2:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

Step3:

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

= 1 / 303

= 1

So, Greatest Common Divisor of 490, 428, 855, 303 is 1
