Greatest Common Divisior

We found the divisors of 805, 781, 202, 164 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 805, 781, 202, 164 is 1.

Therefore, GCD of numbers 805, 781, 202, 164 is 1

Given Input Data is 805, 781, 202, 164

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

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 781 is 11 x 71

Prime Factorization of 202 is 2 x 101

Prime Factorization of 164 is 2 x 2 x 41

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(805, 781) = 628705

GCD(805, 781) = ( 805 x 781 ) / 628705

GCD(805, 781) = 628705 / 628705

GCD(805, 781) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 202

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

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

GCD(1, 202) = 202 / 202

GCD(1, 202) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 164

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

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

GCD(1, 164) = 164 / 164

GCD(1, 164) = 1

GCD of 805, 781, 202, 164 is 1
