Make use of GCD Calculator to determine the Greatest Common Divisor of 86, 90, 30 i.e. 2 largest integer that divides all the numbers equally.
GCD of 86, 90, 30 is 2
GCD(86, 90, 30) = 2
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 86, 90, 30 is 2
GCD(86, 90, 30) = 2
Given Input numbers are 86, 90, 30
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 86
List of positive integer divisors of 86 that divides 86 without a remainder.
1, 2, 43, 86
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 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Greatest Common Divisior
We found the divisors of 86, 90, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 90, 30 is 2.
Therefore, GCD of numbers 86, 90, 30 is 2
Given Input Data is 86, 90, 30
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 86 is 2 x 43
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 30 is 2 x 3 x 5
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(86, 90) = 3870
GCD(86, 90) = ( 86 x 90 ) / 3870
GCD(86, 90) = 7740 / 3870
GCD(86, 90) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 30
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 30) = 30
GCD(2, 30) = ( 2 x 30 ) / 30
GCD(2, 30) = 60 / 30
GCD(2, 30) = 2
GCD of 86, 90, 30 is 2
