Therefore, GCD of numbers 891, 900, 43, 128 is 1

Given Input Data is 891, 900, 43, 128

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

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 900 is 2 x 2 x 3 x 3 x 5 x 5

Prime Factorization of 43 is 43

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

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(891, 900) = 89100

GCD(891, 900) = ( 891 x 900 ) / 89100

GCD(891, 900) = 801900 / 89100

GCD(891, 900) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 43

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

LCM(9, 43) = 387

GCD(9, 43) = ( 9 x 43 ) / 387

GCD(9, 43) = 387 / 387

GCD(9, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 128

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

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

GCD(1, 128) = 128 / 128

GCD(1, 128) = 1

GCD of 891, 900, 43, 128 is 1
