Composite Numbers

When referring to positive integers, prime means having only two factors and composite means having more than two.

No. 5 goes into it because of the division rule of five: If it ends in zero or five, it is divisible by 5.

609 is a composite number. Its positive integer factors are:

1, 3, 7, 21, 29, 87, 203, 609

It has more than two factors.

1

All even numbers are composite numbers except for 2 itself which is a prime number.

189 = 3 x 3 x 3 x 7

It's composite.

There are lots of numbers which are neither. For example, pi, -7, 0, 1, sqrt(7).

Composite. All positive, whole numbers greater than five and ending in 0, 2, 4, 5, 6 or 8 are composite.

It is just 1

Every irrational number, every rational number which is not an integer and every integer less than 2 falls into this category.

125 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.

2500 is a composite number. A prime number has exactly 2 factors, 1 and the number itself. All even numbers greater than 2 (numbers ending in 2, 4, 6, 8, or 0) are composites because they have more than 2 factors.

523 is a prime number. Its only positive integer factors are itself and 1.

A composite is any number that has a prime factor smaller than itself and greater than 1.

236 is a composite number. Its positive integer factors are:

1, 2, 4, 59, 118, 236

101 is a prime number because its only factors are 1 and itself; 101.

639 is a composite number. Its positive integer factors are:

1, 3, 9, 71, 213, 639

29

70 is a composite number as it is divisible by 1, 2, 5, 7, 10, 14, 35, 70

4, 10, 20, 25, 50, 100 are the composite factors of 100.

It is even, so divisible by 2. Therefore it is composite. So the answer is yes.
