Prime Factors of 124

Steps to find Prime Factors of 124 by Division Method

To find the primefactors of 124 using the division method, follow these steps:

• Step 1. Start dividing 124 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 124, which is 2. Divide 124 by 2 to obtain the quotient (62).
  124 ÷ 2 = 62
• Step 3. Repeat step 1 with the obtained quotient (62).
  62 ÷ 2 = 31
  31 ÷ 31 = 1

So, the prime factorization of 124 is, 124 = 2 x 2 x 31.

Steps to find Prime Factors of 124 by Factor Tree Method

We can follow the same procedure using the factor tree of 124 as shown below:

So, the prime factorization of 124 is, 124 = 2 x 2 x 31.

What does Prime factor of a number mean?

A prime number in mathematics is defined as any natural number greater than 1, that is not divisible by any number except 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 124 are 2 x 2 x 31.

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 124 but not a prime factor of 124.
