Prime Numbers

positive

Every multiple of 24 is a common multiple of 2, 6 & 8. Where did "three" come from?

5 x 41 = 205

No exponents are needed.

3 x 3 + 3 + (3+3)/3

5 x 7 x 31 = 1085

4 is a prime factor of 20 whereas it isn't a factor of 50.

8000 is a composite number. It is an even number that ends in zero. It is divisible by 2, 5 and 10.

No, all whole numbers larger than two that end in the number 2 are composite.

211 is a prime number.

No, because it is simply never ending. So you would not be able to know what it can be divided by.

The prime factors of 900 are 2x2x3x3x5x5.

The only two prime factors of 4625 are: 5, 37

It is: 24

20 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.

It's 7,654,321 .

The GCF is 2.

2,401=7x7x7x7, so it is composite.

you will no when you can no longer multiply waht ever nuumber

example 4 you have 1 and 2 cause 1 times 4 and 2 times 2 now i can no longer do anything with that number so i now no the prime factors

hope this helps

I assume that if your 11 years old, you're in Grade 6, right?

Anyway, 1 is not a prime number or a composite number. A prime number is a number with only two factors: 1 and itself, while a composite number is a number with more than two factors. 1 is not either of those because its only factor is 1. Therefore, you could say it's a "special number".

6, with factors 1, 2, 3 and 6.

2 x 2 x 5 x 7 x 61 = 8540

Richard Dedekind came up the concept of Dedekind cuts, which have since become the standard definition of real numbers. A Dedekind cut for a real number x is the subset of all numbers such that are smaller than or equal to x.
