How can I factor \(27 + 12\)?

= 27 + 12 3 is common in both of them so = 3 (9 + 4) The answer is 3(9+4).

Firstly look for the highest number which goes into both of them:
1 goes into both of them 3 goes into both of them and is the highest so we use this one.
Next write a 3 outside a set of brackets: 3 ( )
Then, the point of these brackets is that you times everything inside them by 3 so in order to get the numbers inside, you divide both by 3.
27 ÷ 3 = 9 12 ÷ 3 = 4
So now put these back into the brackets and you're done:
3 ( 9 + 4 )
Try to factorise 18 + 12 now to make sure you understand.

The expression 27 + 12 can be factored by identifying the greatest common factor, which is 3. By factoring out 3, the expression simplifies to 3 ( 9 + 4 ) or 3 ( 13 ) .
