HCF and LCM
Think about how I would solve the problem and from there i can tell which method my answer would be.Foo Lin Hui23

If the question needs or asks for the lowest possible number that all the numbers can multiply by another number to obtain it, I will use LCM.Sofia Pineda Radivojevic33

If the question is about dividing things into equal lengths, I would put it as HCF. If it is about how things will meet together, I would put it as LCM.Annie41

See what specific value does the question ask for. Some questions require us to find the HCF or LCM or both value the equate the answer.

I use HCF if the question needs us to divide some numbers. I use LCM if the question requires us to to find the multiples of the numbers. Wan Hanafi243

when you want to find a common meeting point of the numbers, use LCM. when you want to find the value of numbers divide by a common factor, use HCF.

When the question ask what is the highest possible answer then use HCF/ when they ask what is the time they will meet again it will be LCM
