Make use of GCD Calculator to determine the Greatest Common Divisor of 78, 73, 22, 80 i.e. 1 largest integer that divides all the numbers equally.
GCD of 78, 73, 22, 80 is 1
GCD(78, 73, 22, 80) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 78, 73, 22, 80 is 1
GCD(78, 73, 22, 80) = 1
Given Input numbers are 78, 73, 22, 80
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 78

1, 73
Divisors of 22
List of positive integer divisors of 22 that divides 22 without a remainder.
1, 2, 11, 22
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
Greatest Common Divisior
We found the divisors of 78, 73, 22, 80 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 78, 73, 22, 80 is 1.
Therefore, GCD of numbers 78, 73, 22, 80 is 1
Given Input Data is 78, 73, 22, 80
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 73 is 73
Prime Factorization of 22 is 2 x 11
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
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(78, 73) = 5694
GCD(78, 73) = ( 78 x 73 ) / 5694
GCD(78, 73) = 5694 / 5694
GCD(78, 73) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 22
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 22) = 22
GCD(1, 22) = ( 1 x 22 ) / 22
GCD(1, 22) = 22 / 22
GCD(1, 22) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
GCD(1, 80) = 80 / 80
GCD(1, 80) = 1
GCD of 78, 73, 22, 80 is 1
