UXO game to practice
'Highest common factor' for 6th grade

Find the highest common factor (HCF)
of sets of 2 or 3 numbers

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:

  1. Find the factors of each number.
  2. Identify which factors are common to all the numbers.
  3. Determine the largest of these common factors.

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 UXO 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.

UXO is a click to clear game with multiple targets at different levels

Large thumbnail for math game UXO

UXO is a fun game to learn math where you attempt to knock over all the target objects while avoiding clicking / tapping on the bombs.

After each level, win an additional 50 points by correctly answering a math question from your selected topic. Wrong answers lose you 20 points but you can answer multiple times. Each level lasts 30 seconds: if you haven't cleared all the targets in that time, you lose 50 points. High scores can be added to the UXO leaderboards.


Notes

  • This is a fast-paced game of clicking or dragging over moving targets.
  • Also suitable for tablets and mobiles (it's actually easier than with a mouse)
  • Answer math questions correctly for a higher score
  • Hit all the targets in 30 seconds or you lose points.
