To factor the expression \( 24s + 40 \), we first look for the greatest common factor (GCF) of the two coefficients 24 and 40.
The factors of 24 are:
- 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are:
- 1, 2, 4, 5, 8, 10, 20, 40
The greatest common factor (GCF) of 24 and 40 is 8.
Now we can factor out 8 from the expression:
\[ 24s + 40 = 8(3s + 5) \]
Thus, the factored form of \( 24s + 40 \) is:
\[ 8(3s + 5) \]
Here, \( 8 \) is the whole number greater than 1.
