Make use of GCD Calculator to determine the Greatest Common Divisor of 77, 38, 65 i.e. 1 largest integer that divides all the numbers equally.
GCD of 77, 38, 65 is 1
GCD(77, 38, 65) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 77, 38, 65 is 1
GCD(77, 38, 65) = 1
Given Input numbers are 77, 38, 65
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 77
List of positive integer divisors of 77 that divides 77 without a remainder.
1, 7, 11, 77
Divisors of 38
List of positive integer divisors of 38 that divides 38 without a remainder.
1, 2, 19, 38
Divisors of 65
List of positive integer divisors of 65 that divides 65 without a remainder.
1, 5, 13, 65
Greatest Common Divisior
We found the divisors of 77, 38, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 77, 38, 65 is 1.
Therefore, GCD of numbers 77, 38, 65 is 1
Given Input Data is 77, 38, 65
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 77 is 7 x 11
Prime Factorization of 38 is 2 x 19
Prime Factorization of 65 is 5 x 13
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(77, 38) = 2926
GCD(77, 38) = ( 77 x 38 ) / 2926
GCD(77, 38) = 2926 / 2926
GCD(77, 38) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
GCD(1, 65) = 65 / 65
GCD(1, 65) = 1
GCD of 77, 38, 65 is 1
