Prime Numbers

It is prime.

There is no such thing as a "trasport number".

2 x 2 x 2 x 2 = 16

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. 53 is prime.

More. There are 116 of them.

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. 1000 is composite.

1, 2, 4, 5, 10, 19, 20, 25, 38, 50, 76, 95, 100, 190, 380, 475, 950, 1900

It is a number for which the sum of the proper divisors is less the the number.

Example: 21 has divisors 1, 3, and 7. The sum is 11 which is less than 21.

Note: All prime numbers are deficient and as there are an infinite number of them, there are an infinite set of deficient numbers too.

The prime factors of 333 are 3 and 37.

They are 2 and 7.

3 x 173 = 519

20,2

10,2,2

5,2,2,2

It is: 101

Yes, two integers with no common prime factors are called "relatively prime." Fractions that are less than 1 and in "simplified form" have numerators and denominators that are relatively prime, so they cannot be further reduced.

2^2*3 = 12

2*3^2 = 18

223 is a prime number. It is only evenly divisible by itself and one.

2 x 11 = 22

yes beacause

First, draw a dot. Below that, draw two dots. Then, 3 dots below it and so on.

Here, you should see the pattern of the triangular number, which is the sum of consecutive integers starting at 1. The terms of that pattern are 1, 3, 6, 10, 15, ....n(1 + n)/2 where n is the total number of dots for the pattern.

2 x 2 x 5 = 20

2 x 2 x 2 = 8

The factors of 333 are 1, 3, 9, 37, 111, and 333, and the prime factorization is 3 x 3 x 37.

2 x 11 x 13 = 286

728 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 have a different name.
