- All the multiples of 31 are numbers that can be divided by 31 without leaving a comma spot.
- It is not reasanoble to list all multiples of 31, because this list would be an infinite number of multiples of thirty-one. This is why we show the multiplication table to the first one hundred multiples of 31.

- 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 3.**Three is the first odd prime number and the second smallest right after number two. At the same time it is the first Mersenne prime (2 ^ 2-1), the first Fermat prime (2 ^ {2 ^ 0} +1), the second Sophie Germain prime and the second Mersenne prime exponent. It is the fourth number of the Fibonacci sequence and the second one that is unique. The triangle is the simplest geometric figure in the plane. With the calculation of its sizes deals trigonometry. Rule of three: If the sum of the digits of a number is a multiple of three, the underlying number is divisible by three.**About Number 1.**The number 1 is not a prime number, but a divider for every natural number. It is often taken as the smallest natural number (however, some authors include the natural numbers from zero). Your prime factorization is the empty product with 0 factors, which is defined as having a value of 1. The one is often referred to as one of the five most important constants of analysis (besides 0, p, e, and i). Number one is also used in other meanings in mathematics, such as a neutral element for multiplication in a ring, called the identity element. In these systems, other rules can apply, so does 1 + 1 different meanings and can give different results. With 1 are in linear algebra and vectors and one Einsmatrizen whose elements are all equal to the identity element, and refers to the identity map.

- A number is multiple of thirty-one if it contains the number 31 a particular amount of times. 155 is a multiple of 31 because it contains number 31 five times.
- A number is a multiple of 31 when it is the result of multiplying 31 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.
