Greatest Common Divisior

We found the divisors of 645, 701, 60, 521 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 701, 60, 521 is 1.

Therefore, GCD of numbers 645, 701, 60, 521 is 1

Given Input Data is 645, 701, 60, 521

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 701 is 701

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 521 is 521

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(645, 701) = 452145

GCD(645, 701) = ( 645 x 701 ) / 452145

GCD(645, 701) = 452145 / 452145

GCD(645, 701) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 60

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

LCM(1, 60) = 60

GCD(1, 60) = ( 1 x 60 ) / 60

GCD(1, 60) = 60 / 60

GCD(1, 60) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 521

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

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

GCD(1, 521) = 521 / 521

GCD(1, 521) = 1

GCD of 645, 701, 60, 521 is 1
