Therefore, GCD of numbers 840, 332, 985, 488 is 1

Given Input Data is 840, 332, 985, 488

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 332 is 2 x 2 x 83

Prime Factorization of 985 is 5 x 197

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(840, 332) = 69720

GCD(840, 332) = ( 840 x 332 ) / 69720

GCD(840, 332) = 278880 / 69720

GCD(840, 332) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 985

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

LCM(4, 985) = 3940

GCD(4, 985) = ( 4 x 985 ) / 3940

GCD(4, 985) = 3940 / 3940

GCD(4, 985) = 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 840, 332, 985, 488 is 1
