Multiples and Common Multiples

MULTIPLES
Multiples of a number are the
products you get when you
multiply that number by the
numbers 1,2,3,4 and so on.

MULTIPLES
The multiples of a number can
be divided by that number
without remainder.

Give the first 12
multiples
of 3.

To find the multiples
of 3, you can simply
multiply 3 by 1,2,3,4
and so on.

3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
3 x 11 = 33
3 x 12 = 36

You can also use
skip counting.

Multiples of 3:
3,6,9,12,15,18,21,24,27,
30,33,36

You can also use
the HUNDRED
CHART.

Multiples of 3 =
3,6,9,12,15,18,21,24,27,30,33,36,…
Multiples of 15 =
15,30,4,60,75,90,105,120,135,……
The number of multiples of
a given number is infinite.

COMMON MULTIPLES
are those numbers that are
multiples of all numbers given.

Give the
common
multiples of
2 and 3….

First list down
the multiples of
each number.

Multiples of 2 =
2,4,6,8,10,12,14,16,18,
20,22,24…

Multiples of 3 =
3,6,9,12,15,18,21,24,
27,30,33,36,…

Multiples of 2 =
2,4,6,8,10,12,14,16,18,20,22,24
…
Multiples of 3 =
3,6,9,12,15,18,21,24,27,30,33,3
6,…

Multiples of 2 =
2,4,6,8,10,12,14,16,18,20,22,24…
Multiples of 3 =
3,6,9,12,15,18,21,24,27,30,33,36,…
The common
multiples of 2 and 3 are
6,12,and 24.

• Every multiple of a number is greater
than or equal to that number.
• The number of multiples of a given
number is infinite.
• Every number is a multiple of itself.
POINTS TO REMEMBER
contd

FACTOR OR MULTIPLE?
For each of numbers in the statements, select
either multiple [M] or factor [F]
 34 × 5 = 170
[F] [M] [F] [M] [F] [M]
 25 × 4 = 100
[F] [M] [F] [M] [F] [M]
 90 × 10 = 900
[F] [M] [F] [M] [F] [M]
 45 × 6 = 270
[F] [M] [F] [M] [F] [M]
 7 × 30 = 210
[F] [M] [F] [M] [F] [M]

State whether the following
statements are TRUE or FALSE
1. 1 is a factor of every number. F T
2. The largest factor of any number is the number itself. F
T
3. Number of factors of a given number is infinite. F T
4.The number of multiples of 5 is 10. F T
5.The factors of 65 are 1, 5 and 13 only. F T
( Click ‘F’ for false and ‘T’ for true )
