Hope this helps. This is actually a topic tested in secondary one and two. Its called common factors and common multiples. Have a search about it to find out more!

Thanks..
It’s actually covered in Primary 4. But not as a product of prime factors.
Primary 4 students list out the factors one by one for numbers up to 100.
