Answer:
How many composite numbers are between 1 and 100?
74
Explanation:
Note that the following answer assumes that "between 1 and 100" is intended to include
1
and
100
, following common English usage.
Start with the numbers
1
,
2
,
3
,
...
100
1
is not composite, because it's a unit, so that leaves
99
other numbers.
The numbers
4
=
2
2
,
6
,
8
,
...
,
100
are all divisible by
2
, so composite. There are
100
−
4
2
+
1
=
49
of these, leaving
99
−
49
=
50
other numbers.
The numbers
9
=
3
2
,
15
,
21
,
...
,
99
are all divisible by
3
and not by
2
. There are
99
−
9
6
+
1
=
16
of these, leaving
50
−
16
=
34
other numbers.
The numbers
25
=
5
2
,
35
,
55
,
65
,
85
,
95
are all divisible by
5
and not by
2
or
3
. There are
6
of these, leaving
34
−
6
=
28
other numbers.
The numbers
49
=
7
2
,
77
,
91
are divisible by
7
and not by
2
,
3
or
5
. There are
3
of these, leaving
28
−
3
=
25
other numbers.
These
25
numbers must be prime, since
11
2
=
121
>
100
So the total number of composite numbers is:
49
+
16
+
6
+
3
=
74
