PRIME FACTORISATION Prime factorisation is the process by which a composite number is rewritten as the product of prime factors.Example 1: Find out the prime factorisation of 30. First we will see whether the given number is divisible by a least prime number. Yes, it is, because the digit at its ones place is 0. 30 = 2 × 15 We have, 15 = 3 × 5So, the factors of 30 … [Read more...] about How to Find The Prime Factors Using Factor Tree
