Make use of GCD Calculator to determine the Greatest Common Divisor of 80, 60, 45, 89 i.e. 1 largest integer that divides all the numbers equally.
GCD of 80, 60, 45, 89 is 1
GCD(80, 60, 45, 89) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 80, 60, 45, 89 is 1
GCD(80, 60, 45, 89) = 1
Given Input numbers are 80, 60, 45, 89
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 60
List of positive integer divisors of 60 that divides 60 without a remainder.
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Divisors of 45
List of positive integer divisors of 45 that divides 45 without a remainder.
1, 3, 5, 9, 15, 45
Divisors of 89
List of positive integer divisors of 89 that divides 89 without a remainder.
1, 89
Greatest Common Divisior
We found the divisors of 80, 60, 45, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 60, 45, 89 is 1.
Therefore, GCD of numbers 80, 60, 45, 89 is 1
Given Input Data is 80, 60, 45, 89
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 60 is 2 x 2 x 3 x 5
Prime Factorization of 45 is 3 x 3 x 5
Prime Factorization of 89 is 89
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, 60) = 240
GCD(80, 60) = ( 80 x 60 ) / 240
GCD(80, 60) = 4800 / 240
GCD(80, 60) = 20
Step2:
Here we consider the GCD from the above i.e. 20 as first number and the next as 45
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(20, 45) = 180
GCD(20, 45) = ( 20 x 45 ) / 180
GCD(20, 45) = 900 / 180
GCD(20, 45) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 89
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 89) = 445
GCD(5, 89) = ( 5 x 89 ) / 445
GCD(5, 89) = 445 / 445
GCD(5, 89) = 1
GCD of 80, 60, 45, 89 is 1
