Hi :)
Let's find the (HCF) of 27 and 90
To find that lets first list all the factors of 27
27 : 1, 3, 9 , 27
Now lets do the same thing with 90
90 : 1, 2, 3, 5, 6 , 9, 15...90
Well the hcf is basically the highest common factor
highest = largest
common = both numbers have it
factor = a number that is evenly divided into a larger number
So the hcf of these two numbers is :
9
