### Txtbk Question (pg 9 ques #25 and #26)

The Prime factorisation of a number is 2^4 X 3^5 X 7^2 X 11.

Write down 3 factors of the number that are greater than 100.

(Hint: 16 X 11 = 176, which is a factor.)

answer: 144, 147 and 198

solution: there are a lot of answers for this question. I came out with these answers through multiplying the factors.

144 --> 2^4 x 3^2

147 --> 3 x 7^2

198 --> 11 x 3^2 x 2

The Prime factorisation of two numbers are 2 X 3^2 X 7^3 X 13 and3 X 7^2 X 13^3 X 17 .

Write down 3 common factors of the numbers.

answer: 3, 7 and 13

solution: the common prime factors in both equations are 3, 7 and 13. since they are the same factor in different equation, the equation's answer will surely be able to be divided by the same factor.
