Therefore, GCD of numbers 705, 670, 43, 798 is 1

Given Input Data is 705, 670, 43, 798

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

Prime Factorization of 705 is 3 x 5 x 47

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 43 is 43

Prime Factorization of 798 is 2 x 3 x 7 x 19

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(705, 670) = 94470

GCD(705, 670) = ( 705 x 670 ) / 94470

GCD(705, 670) = 472350 / 94470

GCD(705, 670) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 43

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

LCM(5, 43) = 215

GCD(5, 43) = ( 5 x 43 ) / 215

GCD(5, 43) = 215 / 215

GCD(5, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 798

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

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

GCD(1, 798) = 798 / 798

GCD(1, 798) = 1

GCD of 705, 670, 43, 798 is 1
