Composite Numbers

4

119 is one example.

6 is a composite number because it is the product of two smaller integers, 2 and 3.

Composite.

The three composite numbers are 28, 30 and 32. Their sum is 90.

75 has six factors.

The GCF of all the composite numbers under 100 is 1.

For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.

64 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

There are infinitely many such pairs.

For example,

suppose p, q, r and s are 4 prime numbers.

Then p*q and r*s are both composite but p*q and r*s are coprime.

And you could always mutiply either one of them by the prime number t, and maybe the other one by another r to give p*q*t and r2*s. And so on.

So, for example 2*7 = 14

and 3*5 = 15 form such a pair.

32, 33, 34, 35, 36, 38, 39, 40

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 1597 is a prime number.

The square root of a composite number is not always an irrational number.

e.g. 4 is a composite number and its square root is 41/2 = 2, which is rational number.

Not if the composite number is a multiple of the prime number.

18.

The first ten composite numbers are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18

10 = 2 x 5

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30.

Negative numbers can be classified as either prime or composite because they still have their absolute value

All even numbers, except 2, are composite.

Including 50, there are 34.

6, 8, 10, 14, 15, 21, 22, 26, 27, 33, 34, 35, 38, 39, 46 have exactly four factors.

964 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

753 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30 are the composite numbered dates in September.
