Which of the following is a composite number?<br> A. 31<br> B. 63<br> C. 61<br> D. 13
sashaice [31]

Number  63 is a composite number

<h3>Further explanation</h3>

Numbers are quantities used in measurements

Numbers in mathematics can be divided into several terms

  • 1. integer

numbers consist of positive, negative and 0 numbers

  • 2. natural numbers

numbers consisting of positive numbers, starting with number 1

  • 3. whole number

a number consists of positive numbers and zeros

  • 4. prime number

numbers that can only be divided by numbers themselves and the number 1

And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.

Integers themselves consist of

  • 1. positive integers

the number to the right of the number 0 is 1,2,3 ...

  • 2. negative integers

the numbers to the left of the zeros are -1, -2, -3 ...

  • 3. number 0

A composite number is a positive integer that is not a prime number or can be stated: A whole number that can be made by multiplying other whole numbers

Let's look at the answer choices

  • A. 31

Is a prime number, because it can only be divided by 1 and the number itself (31)

  • B. 63

A composite number, because it can be divided by 3, and the product of 2 numbers is:

21 x 3 and

9 x 7

  • C. 61

Is a prime number, because it can only be divided by 1 and the number itself (61)

  • D. 13

Is a prime number, because it can only be divided by 1 and the number itself (13)
