Given numbers are 455, 454, 812, 130

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 454 are 2 x 227

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 455, 454, 812, 130

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

Apply this formula for all numbers.

Step1:

LCM(455, 454) = 206570

GCD(455, 454) = ( 455 x 454 ) / 206570

= 455 / 454

= 455

Step2:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 455, 454, 812, 130 is 1
