This problem requires us to find a number from the given options that is divisible by both 37 and 8. We can determine this by checking the divisibility rules for both numbers.
A number is divisible by 8 if the number formed by its last three digits is divisible by 8. Let's examine the last three digits of each option:
There is no simple shortcut rule for divisibility by 37. We typically check this by performing the division. Alternatively, since 37 and 8 are coprime (meaning they share no common factors other than 1), any number divisible by both must also be divisible by their least common multiple (LCM), which is their product: $37 \times 8 = 296$.
We will test each number for divisibility by 8 and then by 37 (or by 296).
| Number | Divisibility by 8 Check | Divisibility by 37 Check | Divisible by Both 37 and 8? |
|---|---|---|---|
| 15370 |
Last three digits are 370. Calculation: $370 \div 8 = 46$ with a remainder of 2. Not divisible by 8. |
Calculation: $15370 \div 37 = 415$ with a remainder of 15. Not divisible by 37. | No |
| 14208 |
Last three digits are 208. Calculation: $208 \div 8 = 26$. Divisible by 8. |
Calculation: $14208 \div 37 = 384$. Divisible by 37. | Yes |
| 13702 |
Last three digits are 702. Calculation: $702 \div 8 = 87$ with a remainder of 6. Not divisible by 8. |
Calculation: $13702 \div 37 = 370$ with a remainder of 12. Not divisible by 37. | No |
| 15659 |
Last three digits are 659. Calculation: $659 \div 8 = 82$ with a remainder of 3. Not divisible by 8. |
Calculation: $15659 \div 37 = 423$ with a remainder of 8. Not divisible by 37. | No |
As mentioned earlier, a number divisible by both 37 and 8 must be divisible by their LCM, which is 296.
Let's check the division by 296 for each option:
This method also confirms that 14208 is the only number divisible by 296.
Based on the divisibility checks, the number 14208 is divisible by 8 (since 208 is divisible by 8) and also divisible by 37 (as $14208 / 37 = 384$). Therefore, 14208 satisfies the condition of being divisible by both 37 and 8.
