Make use of GCD Calculator to determine the Greatest Common Divisor of 238, 764, 65, 665 i.e. 1 largest integer that divides all the numbers equally.
GCD of 238, 764, 65, 665 is 1
GCD(238, 764, 65, 665) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 238, 764, 65, 665 is 1
GCD(238, 764, 65, 665) = 1
Given Input numbers are 238, 764, 65, 665
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 7, 19, 35, 95, 133, 665
Greatest Common Divisior
We found the divisors of 238, 764, 65, 665 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 238, 764, 65, 665 is 1.
Therefore, GCD of numbers 238, 764, 65, 665 is 1
Given Input Data is 238, 764, 65, 665
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 238 is 2 x 7 x 17
Prime Factorization of 764 is 2 x 2 x 191
Prime Factorization of 65 is 5 x 13
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(238, 764) = 90916
GCD(238, 764) = ( 238 x 764 ) / 90916
GCD(238, 764) = 181832 / 90916
GCD(238, 764) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 65) = 130
GCD(2, 65) = ( 2 x 65 ) / 130
GCD(2, 65) = 130 / 130
GCD(2, 65) = 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 238, 764, 65, 665 is 1
