To find the highest common factor (HCF) of two or more numbers, you need to find the largest factor that is common to all of the numbers. Here's how to do it:
For example, find the HCF of 12 and 16:
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 16: 1, 2, 4, 8, 16
Common factors of 12 and 16: 1, 2, 4
The common factors of 12 and 16 are 1, 2, and 4. The greatest common factor among these factors is 4. Therefore, the HCF of 12 and 16 is 4.
Here's another example. Find the HCF of 18 and 24:
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
The common factors of 18 and 24 are 1, 2, 3, and 6. The greatest common factor among these factors is 6. Therefore, the HCF of 18 and 24 is 6.
It's important to note that when dealing with larger numbers, it may be more efficient to use prime factorization to find the HCF.
In this topic you are asked to find the highest common factor of sets of 2 or 3 numbers ranging between 6 and 108.
With our Four in a row math game you will be practicing the topic "Highest common factor" from 6th grade / Number / Multiples Factors Primes / Multiples Factors Primes. The math in this game consists of 16 questions that ask you to identify the Highest Common Factor (HCF) for the given sets of numbers.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
