Given numbers are 310, 909, 910, 420

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 909 are 3 x 3 x 101

Prime factors of 910 are 2 x 5 x 7 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 310, 909, 910, 420

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

Apply this formula for all numbers.

Step1:

LCM(310, 909) = 281790

GCD(310, 909) = ( 310 x 909 ) / 281790

= 310 / 909

= 310

Step2:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 310, 909, 910, 420 is 1
