James thinks of two numbers. He says “The Highest Common Factor (HCF) of my two numbers is 3 The Lowest Common Multiple (LCM) of my two numbers is 45” Write down two numbers that James could be thinking of.

9 , 15

Step-by-step explanation:

HCF = 3

LCM = 45

Product of two numbers = HCF * LCM

                                        = 3*45

                                       = 135

The two numbers are the factors of 135

9 * 15 = 135

9 = 3*3

15 = 3 * 5

HCF = 3

LCM = 3* 3 * 5 = 45

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
