Factors of 2 | Factor Tree of 2

Today we are going to present here Factor Tree of 2. The factor is the number that divides the original number. The factors of 2 are 1 and 2 itself.

Let's test the numbers, starting from 1:

Can 1 divide 2 perfectly?

Yes! 2 ÷ 1 = 2.

This means 1 is a factor of 2. And, as we learned, 1 is always a factor of any number!

Can 2 divide 2 perfectly?

Yes! 2 ÷ 2 = 1.

This means 2 is a factor of 2. And, as we learned, every number is a factor of itself!

Are there any other whole numbers that can divide 2 perfectly?

What about 3? 2 ÷ 3 doesn't give a whole number (it's 0 with a remainder of 2).

What about numbers larger than 2? No, they cannot divide 2 perfectly. For example, 2 divided by 4 is a fraction, not a whole number.

So, it's clear and simple that the only whole numbers that can divide 2 perfectly are 1 and 2.

Therefore, the factors of 2 are 1 and 2.

Prime Factorization of 2

A prime number is a whole number greater than 1 that has only two factors, 1 and the number itself.

Is 2 a prime number?

Yes! It is greater than 1 and its only factors are 1 and 2. It fits the definition perfectly.

The 2 is only Even Prime Number: Almost all prime numbers are odd (like 3, 5, 7, 11...). The only exception to this rule is the number 2! All other even numbers (4, 6, 8, 10...) can always be divided by 2 (and 1 and themselves), so they have at least three factors, making them composite. This makes 2 truly unique and important.
