What is the least prime factor of 4?

Input: N = 4 Output: [0, 1, 2, 3, 2] Explanation: least prime factor of 1 = 1, least prime factor of 2 = 2, least prime factor of 3 = 3, least prime factor of 4 = 2 .

How to find 4 digit prime number?

The digits that are prime numbers are 2, 3, 5 and 7. So for every digit of such an integer as you want you have 4 possibilities. As you want a four-digit number, that gives you 4*4*4*4 = 256 different numbers, from 2222 to 7777 .

What is the smallest 4 digit prime factorization?

Step-by-step explanation: 1000 is the smallest 4-digit number. So, the Prime factorization of 1000 is 2 × 2 × 2 × 5 × 5 × 5 .

What is the prime factorization of 4 and 9?

Prime factorization of 4 and 9 is (2 × 2) and (3 × 3) respectively. As visible, there are no common prime factors between 4 and 9, i.e. they are coprime.

How do you write prime factorization?

When a composite number is written as a product of all of its prime factors, we have the prime factorization of the number . For example, we can write the number 72 as a product of prime factors: 72 = 2 3 ⋅ 3 2 . The expression 2 3 ⋅ 3 2 is said to be the prime factorization of 72.

What is the prime factorization method of 4 and 5?

Prime factorization of 4 and 5 is (2 × 2) and (5) respectively.

What are Factors of 4?

Let us recall the meaning of the word "factor." A factor is a number that divides the number into equal parts. The factors of 4 are integers that divide 4 without leaving any remainder. For example, 2 is a factor of 4 because 2 divides 4 without any remainder. Interestingly, the quotient is also 2.

Important Notes:

Fractions and decimals (numbers that are not integers) cannot be the factors of any number.
When a number is a factor of the given number, then its additive inverse is also a factor of the given number.
For example, since 2 is a factor of 4, -2 is also a factor of 4.
4 is a perfect square and 2² = 4.

How to Calculate the Factors of 4?

Let us learn how to calculate the factors of 4.

Factors of 4 by Prime Factorization

In the process of prime factorization, the number is written as a product of its prime factors. To get the prime factorization of 4, we divide it by its smallest prime factor which is 2 which is 4/2 = 2.

Since 2 is a prime number, it is divisible by 2 only. This process goes on till we get the quotient as 1. The prime factorization of 4 is shown below:

Factors of 4 in Pairs

The pair factors of 4 are obtained by writing 4 as a product of two numbers in all possible ways. In each product, both multiplicands are the factors of 4.

Product that Results in 4	Pair Factors of 4
1 × 4	1, 4
2 × 2	2, 2
4 × 1	4, 1

It is possible to have negative pair factors as well because the product of two negative numbers gives a positive number.

The negative pair factors of 4 are (-1, -4), (-2, -2), and (-4, -1).
