Therefore, GCD of numbers 434, 147, 890, 807 is 1

Given Input Data is 434, 147, 890, 807

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

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 890 is 2 x 5 x 89

Prime Factorization of 807 is 3 x 269

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(434, 147) = 9114

GCD(434, 147) = ( 434 x 147 ) / 9114

GCD(434, 147) = 63798 / 9114

GCD(434, 147) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 890

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

LCM(7, 890) = 6230

GCD(7, 890) = ( 7 x 890 ) / 6230

GCD(7, 890) = 6230 / 6230

GCD(7, 890) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 807

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

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

GCD(1, 807) = 807 / 807

GCD(1, 807) = 1

GCD of 434, 147, 890, 807 is 1
