Question

Helen thinks of two numbers.

The Highest Common Factor (HCF) of her two numbers is 5.
The Lowest Common Multiple (LCM) of her two numbers is a multiple of 12
Write down two possible numbers that Helen could be thinking of.​

Answer 1

let two numbers be n and m

since hcf of these two numbers is 5, so 5 should be in both the numbers.

let n =5

then m = 5 × (12 × p)

you can take p=1

then m = 60

so numbers are 5 and 60

you can also take n = 5×q where q should not be equal to p
