Answer:
15 and 33
Step-by-step explanation:
Composite numbers are the numbers which have more than 2 factors.
Odd Composite numbers whose factors are only odd.
Factor pairs of 15 : -
1 x 15 = 15
3 x 5 = 15
Factors of 15 are 1, 3 and 15.
( 1, 3, and 15 are odd numbers )
Totally 3 factors.
Since, 15 has more than 2 factors and they are also odd.
Hence, 15 is an odd composite numbers.
Factor pairs of 33 : -
1 x 33 = 33
3 x 11 = 33
Factors of 33 are 1, 11 and 33.
( 1, 11, and 33 are odd numbers )
Totally 3 factors.
Since, 33 has more than 2 factors and they are also odd.
Hence, 33 is an odd composite numbers.
Note : -
1 is neither prime nor composite.
3 and 23 are prime numbers.
8, 18 and 28 are even composite numbers.
