We found the divisors of 610, 155, 82, 665 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 610, 155, 82, 665 is 1.

Therefore, GCD of numbers 610, 155, 82, 665 is 1

Given Input Data is 610, 155, 82, 665

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 155 is 5 x 31

Prime Factorization of 82 is 2 x 41

Prime Factorization of 665 is 5 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(610, 155) = 18910

GCD(610, 155) = ( 610 x 155 ) / 18910

GCD(610, 155) = 94550 / 18910

GCD(610, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 82

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

LCM(5, 82) = 410

GCD(5, 82) = ( 5 x 82 ) / 410

GCD(5, 82) = 410 / 410

GCD(5, 82) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 665

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

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

GCD(1, 665) = 665 / 665

GCD(1, 665) = 1

GCD of 610, 155, 82, 665 is 1
