Greatest Common Divisior

We found the divisors of 610, 261, 63, 170 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 610, 261, 63, 170 is 1.

Therefore, GCD of numbers 610, 261, 63, 170 is 1

Given Input Data is 610, 261, 63, 170

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

Prime Factorization of 610 is 2 x 5 x 61

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 170 is 2 x 5 x 17

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(610, 261) = 159210

GCD(610, 261) = ( 610 x 261 ) / 159210

GCD(610, 261) = 159210 / 159210

GCD(610, 261) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 170

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

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

GCD(1, 170) = 170 / 170

GCD(1, 170) = 1

GCD of 610, 261, 63, 170 is 1
