Finding Factors Using Division Method

The division method finds the numbers that fully divide the given number. The steps are given below:
 

Step 1: Since every number is divisible by 1, 1 will always be a factor. Example: 342÷1=342
 

Step 2: Move to the next integer. The factors of the number include the number that is used to divide and the number of times the particular number is divided.

Thus, the factors of 342 are 1, 2, 3, 6, 57, 114, 171, and 342.
 

Prime Factors and Prime Factorization

Multiplying prime numbers to get the given number as their product is called prime factors. A number, when it is simplified using the factors of that number and is expressed in the form of prime factors, is the prime factorization of a number.
 

Prime Factors of 342: Number 342 has three prime factors.
Prime factors of 342: 2, 3, 19

To find the prime factors of 342, we can divide 342 with the prime numbers like 2, 3, and 19 from the list of factors of 342.
 

Step 1: Divide 342 with the prime number 2: 342÷2=171
 

Step 2: Divide 171 with the prime number 3: 171÷3=57
 

Step 3: Divide 57 with the prime number 3: 57÷3=19
 

Step 4: Divide 19 with the prime number 19: 19÷19=1

Prime Factorization of 342: Prime factorization breaks down the prime factors of 342.
Expressed as 21 × 32 × 192

Factor Tree

The prime factorization is visually represented using the factor tree. It helps to understand the process easily. In this factor tree, each branch splits into prime factors.
This tree shows the breakdown of 342 into its prime factors: 2 × 3 × 19.

Problem 1

Can you check whether 342 and 6 are co-prime?

Okay, lets begin

No, 342 and 6 are not co-prime.

Explanation

To check whether the two numbers are co-prime, list their factors first.
Once you have listed the factors, identify the common factors and determine the GCF.
If the GCF is greater than 1, then the numbers are not co-prime.
Factors of 342: 1, 2, 3, 6, 19, 38, 57, 114, 171, 342
Factors of 6: 1, 2, 3, 6
Here, the GCF is 6. So 342 and 6 are not co-prime.
For co-prime, the GCF of numbers should be 1.

Problem 2

Verify whether 342 is a multiple of 19

Okay, lets begin

Yes, 342 is a multiple of 19

Explanation

Multiples of 19 are numbers we get when 19 is multiplied by another number.
19 × 18 = 342, so 342 is a multiple of 19.

Problem 3

Identify the factors of 342 that are perfect squares

Okay, lets begin

The perfect square factors of 342 are 1 and 36.

Explanation

A perfect square is a number we get when the same number is multiplied twice.
The factors of 342 that satisfy this condition are 1 (1×1) and 36 (6×6).

Well explained 👍

Problem 4

Can 3 be used to divide 342?

Okay, lets begin

 Yes,3 can be used to divide 342 completely.

Explanation

The easy method to check is the number is divisible by 3, and the digits are to be summed up. 3 + 4 + 2 = 9. 9 is a multiple of 3.
So, 342 is divisible by 3.

Well explained 👍

Problem 5

Is 342 a prime number?

Okay, lets begin

 No, 342 is not a prime number.

Explanation

 A prime number has only two factors: 1 and itself.
Since 342 has factors other than 1 and 342 (e.g., 2, 3, 6, 19, etc.), it is not a prime number.
