Therefore, GCD of numbers 80, 840, 991, 942 is 1

Given Input Data is 80, 840, 991, 942

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

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

Prime Factorization of 991 is 991

Prime Factorization of 942 is 2 x 3 x 157

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(80, 840) = 1680

GCD(80, 840) = ( 80 x 840 ) / 1680

GCD(80, 840) = 67200 / 1680

GCD(80, 840) = 40

Step2:

Here we consider the GCD from the above i.e. 40 as first number and the next as 991

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

LCM(40, 991) = 39640

GCD(40, 991) = ( 40 x 991 ) / 39640

GCD(40, 991) = 39640 / 39640

GCD(40, 991) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 942

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

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

GCD(1, 942) = 942 / 942

GCD(1, 942) = 1

GCD of 80, 840, 991, 942 is 1
