We found the divisors of 366, 170, 775, 643 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 366, 170, 775, 643 is 1.

Therefore, GCD of numbers 366, 170, 775, 643 is 1

Given Input Data is 366, 170, 775, 643

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

Prime Factorization of 366 is 2 x 3 x 61

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 643 is 643

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(366, 170) = 31110

GCD(366, 170) = ( 366 x 170 ) / 31110

GCD(366, 170) = 62220 / 31110

GCD(366, 170) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 775

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

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

GCD(2, 775) = 1550 / 1550

GCD(2, 775) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 643

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

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

GCD(1, 643) = 643 / 643

GCD(1, 643) = 1

GCD of 366, 170, 775, 643 is 1
