Question

Prime factorisation of 7 and 14 division method photo

Answer 1

Answer:

Hope this helps you.

Step-by-step explanation:

Let us take an example to find prime factors of 210.

We need to divide 210 by the first prime number 2 we get 105.

Now we need to divide 105 by the prime number 3 and we get 35.

Again we need to divide 35 by the prime number 5 and we get 7.

And, again we need to divide 7 by the prime number 7 and we get 1.

Therefore, 210 = 2 × 3 × 5 × 7

In the same way if we find the factor of 14 then, they are 1, 2, 7 and 14. Out of these 2 and 7 are prime numbers.

Therefore, 2 and 7 are prime factors of 14.

Hence, 14 = 2 × 7

Answer 2

Prime Factorisation of 7 = 7 × 1.

Prime Factorisation of 14 = 2 × 7 ×1.

What is Prime Factorisation?

It is the decomposition of or Factorisation of composite number into a product of small numbers.

Example:- 48 = 2×2×2×2×3.
