Two factors that will add up to 15 are 12 and 3. Factors are two numbers that we multiply together to get a product. 12 x 3 = 36. They add up to 15. 12 + 3 = 15.
In mathematics, a factor is the number which when multiplied with others gives the desired number.
Therefore,factors of 36 are: 1,2,3,4,6,9,12,18 and 36.
We have to find two factors of 36 which when added together gives 15. From the factors of 36, we have 12 and 3 whose product gives 36 and the addition gives 15.
Hence, 12 and 3 are the factors that adds up to 15.
