What is the HCF of 8, 9 and 25?
Highest Common Factor of two or more numbers is the largest possible number which divides the given numbers exactly without any remainder.
Answer: HCF of 8, 9 and 25 is 1
We can find the HCF by the following methods
Methods to Find the HCF of 8 9 and 25
- Prime factorization Method
- Listing the common factors method
- Division MEthod
Method 1: HCF of 8, 9 and 25 by Prime Factorization
Let us represent 8, 9 and 25 as a product of its prime numbers by doing Prime factorization
We See that there are no common factors between 8, 9, and 25.
so the universal factor 1 is the only common factor for 8 9 and 25
Method 2: HCF of 8, 9 and 25 by Listing the Common Factors
We See that there are no common factors between 8, 9, and 25. otherthan 1
Therefore HCF of 8 9 and 25 is 1
Method 3: HCF of 8,9 and 25 by division method
Step1: Let us take the largest number (25) as divisor and the smallest number (8) as divided and do the division
Step2:take the remaining value (9) as dividend and the common factor of 8 and 25 from the previous step as our divisor
Since there are no common factors the universal factor 1 is the HCF of 8,9 and 25
You can find the HCF in any of the above methods but the solution will be the same.
