**What is the Divisibility rule for Number 7?**

Number 7 has a different factor rule. There are methods to test if the number 7 is a factor of your given number. Let's consider, for example, 13,468 as the number for which you need to find the Factor calculator

**The first method to check if a number is divisible by the number 7.**

- Consider the last digit; here, it is the number 8.
- Multiply the last digit b by two, so 2×8=16.
- Consider the other digits of the number, i.e., 1346
- Determine the difference between these numbers from the rest of the numbers and double the last digit.
- It means subtracting 16 from 1346=1330.
- Repeat the procedure until you find a number close to 7 or if it is divisible by 7, as it is not a sure thing if 1330 is divisible by 7.
- So keep the procedure continued as shown below.
- The last digit is 0, so 2×0=0
- So 133-0=133. Now to check if 133 is divisible by 7, repeat the steps.
- So 3×2=6
- 13-6=7
- Now number 7 is divisible by 7. So now we know the whole number, i.e., 13468, is divisible by 7.

**The other method is to check if a number is divisible by 7.**

- Consider the numbers in a reversed order.
- So if the number is 13468, we have 8, 6, 4, 3 and 1
- Multiply these numbers by 1, 2, 3, 4, 5, and 6. Repeat or keep the procedure short to keep it to its original length as required. In such case we
- 8 × 1, 6 × 3, 4 × 2, 3 × 6, and 1 ×4
- Add the results of the obtained sum. If the number is divisible by 7, the original number is ultimately divisible by 7. As (8 × 1) + (6 × 3) + (4 × 2) + (3 × 6) + (1 × 4) = 8 + 18 + 8 + 18 + 4 = 56.
- 56 is divisible by seven, so even the original number 13468 is divisible by 7.

**Conclusion**
