- All the multiples of 45 are numbers that can be divided by 45 without leaving a comma spot.
- It is not reasanoble to list all multiples of 45, because this list would be an infinite number of multiples of forty-five. This is why we show the multiplication table to the first one hundred multiples of 45.

- In mathematics, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier or coefficient. If a is not zero, this is equivalent to saying that b/a is an integer with no remainder. If a and b are both integers, and b is a multiple of a, then a is called a divisor of b.
- 14, 49, -21 and 0 are multiples of 7, whereas 3 and -6 are not. This is because there are integers that 7 may be multiplied by to reach the values of 14, 49, 0 and -21, while there are no such integers for 3 and -6.

**About Number 4.**Four is linear. It is the first composite number and thus the first non-prime number after one. The peculiarity of the four is that both 2 + 2 = 4 and 2 * 2 = 4 and thus 2^2 = 4. Four points make the plane of a square, an area with four sides. It is the simplest figure that can be deformed while keeping it's side lengths, such as the rectangle to parallelogram. Space let's us arrange equidistantly a maximum of four points. These then form a tetrahedron (tetrahedron), a body with four identical triangular faces. Another feature of the four is the impossibility of an algebraic equation of higher degree than four square roots using simple arithmetic and basic operations dissolve.**About Number 5.**Integers with a last digit as a zero or a five in the decimal system are divisible by five. Five is a prime number. All odd multiples of five border again with the five (all even with zero). The fifth number of the Fibonacci sequence is a five. Five is also the smallest prime number that is the sum of all other primes which are smaller than themselves. The Five is a Fermat prime: 5 = 2 ^ {2 ^ 1} +1 and the smallest Wilson prime. Number five is a bell number (sequence A000110 in OEIS). There are exactly five platonic bodies. There are exactly five tetrominoes.

- A number is multiple of forty-five if it contains the number 45 a particular amount of times. 225 is a multiple of 45 because it contains number 45 five times.
- A number is a multiple of 45 when it is the result of multiplying 45 by another number.
- Properties: 0 is a multiple of everything (0=0*b). The product of any integer n and any integer is a multiple of n. In particular, n, which is equal to n * 1, is a multiple of n (every integer is a multiple of itself), since 1 is an integer. If a and b are multiples of x then a+b and a-b are also multiples of x.
