Steps to find Prime Factors of 1898 by Division Method

To find the primefactors of 1898 using the division method, follow these steps:

  • Step 1. Start dividing 1898 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 1898, which is 2. Divide 1898 by 2 to obtain the quotient (949).
    1898 ÷ 2 = 949
  • Step 3. Repeat step 1 with the obtained quotient (949).
    949 ÷ 13 = 73
    73 ÷ 73 = 1

So, the prime factorization of 1898 is, 1898 = 2 x 13 x 73.

So, the prime factorization of 1898 is, 1898 = 2 x 13 x 73.

What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 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 1898 are 2 x 13 x 73.

Properties of Prime Factors

  • Two prime factors of a given number are always coprime to each other.
  • 2 is the only even prime factor any number can have.
  • Two prime factors are always coprime to each other.
  • 1 is neither a prime number nor a composite number and also 1 is the factor of every given number. So, 1 is the factor of 1898 but not a prime factor of 1898.
