Make use of GCD Calculator to determine the Greatest Common Divisor of 67, 90, 91 i.e. 1 largest integer that divides all the numbers equally.
GCD of 67, 90, 91 is 1
GCD(67, 90, 91) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 67, 90, 91 is 1
GCD(67, 90, 91) = 1
Given Input numbers are 67, 90, 91
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 67
List of positive integer divisors of 67 that divides 67 without a remainder.
1, 67
Divisors of 90
List of positive integer divisors of 90 that divides 90 without a remainder.
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Divisors of 91
List of positive integer divisors of 91 that divides 91 without a remainder.
1, 7, 13, 91
Greatest Common Divisior
We found the divisors of 67, 90, 91 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 67, 90, 91 is 1.
Therefore, GCD of numbers 67, 90, 91 is 1
Given Input Data is 67, 90, 91
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 67 is 67
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 91 is 7 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(67, 90) = 6030
GCD(67, 90) = ( 67 x 90 ) / 6030
GCD(67, 90) = 6030 / 6030
GCD(67, 90) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
GCD(1, 91) = 91 / 91
GCD(1, 91) = 1
GCD of 67, 90, 91 is 1
