Rewrite the expression as a multiple of a sum of two numbers with no common factor 15+24 _____
nata0808 [166]
<span>To rewrite the expression as a multiple of a sum of two numbers with no common factor, we're supposed to find the greatest common factor between the terms and factor it out. </span>We can see that both 15 and 24 are divisible by 3. So let's factor the 3 out. Since the 3 goes into 15 five times and into 24 eight times, the expression can be rewritten like this.

15 + 24 = 3(5 + 8)
