Therefore, GCD of numbers 920, 155, 92, 488 is 1

Given Input Data is 920, 155, 92, 488

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

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 155 is 5 x 31

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 488 is 2 x 2 x 2 x 61

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(920, 155) = 28520

GCD(920, 155) = ( 920 x 155 ) / 28520

GCD(920, 155) = 142600 / 28520

GCD(920, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 92

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

LCM(5, 92) = 460

GCD(5, 92) = ( 5 x 92 ) / 460

GCD(5, 92) = 460 / 460

GCD(5, 92) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 488

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

LCM(1, 488) = 488

GCD(1, 488) = ( 1 x 488 ) / 488

GCD(1, 488) = 488 / 488

GCD(1, 488) = 1

GCD of 920, 155, 92, 488 is 1
