Prime factorization using repeated division
The prime factors of a number are factors which are prime numbers. We can find the prime factors of a number by repetitive division. This method is called prime factorisation.
Example: Find the prime factors of 36. Solution:
The prime factors of 36 are 2 and 3. We can write 36 as a product of prime factors: 2 × 2 × 3 × 3 To find prime factors using the repetitive division, it is advisable to start with a small prime factor and continue the process with bigger prime factors.
