Make use of GCD Calculator to determine the Greatest Common Divisor of 80, 77, 17 i.e. 1 largest integer that divides all the numbers equally.
GCD of 80, 77, 17 is 1
GCD(80, 77, 17) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 80, 77, 17 is 1
GCD(80, 77, 17) = 1
Given Input numbers are 80, 77, 17
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 80
List of positive integer divisors of 80 that divides 80 without a remainder.
1, 2, 4, 5, 8, 10, 16, 20, 40, 80
Divisors of 77
List of positive integer divisors of 77 that divides 77 without a remainder.
1, 7, 11, 77
Divisors of 17
List of positive integer divisors of 17 that divides 17 without a remainder.
1, 17
Greatest Common Divisior
We found the divisors of 80, 77, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 77, 17 is 1.
Therefore, GCD of numbers 80, 77, 17 is 1
Given Input Data is 80, 77, 17
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 77 is 7 x 11
Prime Factorization of 17 is 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(80, 77) = 6160
GCD(80, 77) = ( 80 x 77 ) / 6160
GCD(80, 77) = 6160 / 6160
GCD(80, 77) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
GCD(1, 17) = 17 / 17
GCD(1, 17) = 1
GCD of 80, 77, 17 is 1
