Therefore, GCD of numbers 155, 456, 151, 489 is 1

Given Input Data is 155, 456, 151, 489

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 155 is 5 x 31

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

Prime Factorization of 151 is 151

Prime Factorization of 489 is 3 x 163

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(155, 456) = 70680

GCD(155, 456) = ( 155 x 456 ) / 70680

GCD(155, 456) = 70680 / 70680

GCD(155, 456) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 151

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

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

GCD(1, 151) = 151 / 151

GCD(1, 151) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 489

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

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

GCD(1, 489) = 489 / 489

GCD(1, 489) = 1

GCD of 155, 456, 151, 489 is 1
