what is a easy way to factor multiples of a number?

Answer 1

Are you asking for factoring, or multiplying?

Factoring is breaking it down into the parts that multiple to be the number. The usual way is to divide it using prime factorization. Perhaps an easier way is to try an think of a couple of factors. Then try to factor those, until you get everything factored.

For example, let's say you had to factor 1000. You could break it down into 10 x 100.

Then you could break 10 into 2 x 5, and 100 into 10 x 10.

So now you have (2 x 5) x (10 x 10)

Then you can factor each of the tens again:
(2 x 5) x (2 x 5) x (2 x 5)

Now they are all prime, so you are done. Put them in order and you have:
1000 = 2 x 2 x 2 x 5 x 5 x 5

These are often drawn as "factor trees"

........ 1000
........../ ....\
..... 10 .... 100
...../ . \ .... / .... \
....2 . 5 .. 10 ..10
............. / . \ . / . \
............ 2 . 5 2 . 5

Then just read the "leaves" to get:
1000 = 2 x 2 x 2 x 5 x 5 x 5

Answer 2

Use a prime number tree. the primes as multiples will be the factors

Answer 3

for me its just dividing that number by 1 to 9....that way it brings most of the multiples if not all...if its a small number like 16....16/2...16/3....and so on....big number....calculator

Answer 4

find the least common denominator(s) or number(s) that that particular number goes into evenly, the a factoring tree, or the slide method.

Answer 5

well you can always start with 2 and work your way up.

say yiu have

186 <------ the number two goes into it
93 <--------- we know 2 doesn't go into it so we go to 3
31 <----- a prime number so...

the factors are 2x3x31

Answer 6

factoring tree.
