Prime Factors of 1292

Steps to find Prime Factors of 1292 by Division Method

To find the primefactors of 1292 using the division method, follow these steps:

• Step 1. Start dividing 1292 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 1292, which is 2. Divide 1292 by 2 to obtain the quotient (646).
  1292 ÷ 2 = 646
• Step 3. Repeat step 1 with the obtained quotient (646).
  646 ÷ 2 = 323
  323 ÷ 17 = 19
  19 ÷ 19 = 1

So, the prime factorization of 1292 is, 1292 = 2 x 2 x 17 x 19.

Steps to find Prime Factors of 1292 by Factor Tree Method

We can follow the same procedure using the factor tree of 1292 as shown below:

So, the prime factorization of 1292 is, 1292 = 2 x 2 x 17 x 19.

How do you define Prime Factors of a number?

Prime numbers, in mathematics are all those natural numbers greater than 1 that have exactly 2 factors which are 1 and the number itself. When we express any number as the product of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 1292 are 2 x 2 x 17 x 19.

Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• Any number can have only 1 even prime factor and that is number 2.
• Two prime factors are always coprime to each other.
• 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 1292 but not a prime factor of 1292.
