Can a multiple 9 be a factor of 3?
First, realise that you do not need to consider the 3 at all. It is a factor of 9, so any multiple 9 is a factor of 3. Second: Notice that 4 and 9 do not have any common factor, so the LCM has to have all the factors of 4 and 9 Look at the product of the prime factors:
How to write down multiples of 4, 9, 3?
Method 1: Write down multiples of 4, 9 and 3. If you don’t get a common number soon, then write down more multiples. Or you can quit Method 1 and move onto Method 2. Speaking of Method 2, now you’re going to learn about it! Method 2: Write down multiples of 9.
Are there any numbers that are multiples of 3?
Multiples of 3. Any number that can be denoted in the form 3n where n is an integer is the multiples of 3. So if two values p and q are there, we say that q is a multiple of p if q = np for some integer n. Some of the multiples of 3 include, 6, 18, 21, 300, 60, etc.
