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.

(3,45) and (15,9)

Step-by-step explanation:

LCM x HCF = 45*3 = 135

so, the pairs which has HCF as 3 and LCM as 45 are (3,45) and (15,9)

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
