The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 911.
The divisibility rule for 911 is a method by which we can determine if a number is divisible by 911 without using the division method. Check whether 1822 is divisible by 911 with the divisibility rule.
Step 1: Separate the number into two equal parts. For 1822, the parts are 18 and 22.
Step 2: Subtract the larger part from the smaller part. Here, 22 - 18 = 4.
Step 3: If this result is zero or a multiple of 911, the number is divisible by 911. In this case, 4 is not a multiple of 911, so 1822 is not divisible by 911.
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 911.
Memorize the multiples of 911 (911, 1822, 2733, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 911, then the number is divisible by 911.
If the result we get after the subtraction is negative, we will ignore the symbol and consider it as positive for checking the divisibility of a number.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 911. For example, check if 3644 is divisible by 911 using the divisibility test. Separate the number into equal parts, 36 and 44. Subtract the larger part from the smaller part, 44 - 36 = 8. Since 8 is not a multiple of 911, 3644 is not divisible by 911.
Students can use the division method as a way to verify and crosscheck their results. This will help them verify and also learn.
The divisibility rule of 911 helps us quickly check if a given number is divisible by 911, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes to avoid.
Is 3644 divisible by 911?
No, 3644 is not divisible by 911.
To determine if 3644 is divisible by 911, use the divisibility rule for 911.
1. Multiply the last three digits of the number by 3, 644 × 3 = 1932.
2. Subtract the result from the remaining digits excluding the last three, 3 – 1932 = -1929.
3. Since -1929 is not a multiple of 911, 3644 is not divisible by 911.
Check the divisibility rule of 911 for 5466.
No, 5466 is not divisible by 911.
To check if 5466 is divisible by 911:
1. Multiply the last three digits by 3, 466 × 3 = 1398.
2. Subtract the result from the remaining digits, excluding the last three, 5 – 1398 = -1393.
3. Since -1393 is not a multiple of 911, 5466 is not divisible by 911.
Is 9110 divisible by 911?
Yes, 9110 is divisible by 911.
To verify divisibility of 9110 by 911:
1. Multiply the last three digits by 3, 110 × 3 = 330.
2. Subtract the result from the remaining digits excluding the last three, 9 – 330 = -321.
3. Since -321 is not a direct multiple of 911, adjust the calculation to include the original number: 9110 ÷ 911 = 10, which confirms divisibility.
Can 1822 be divisible by 911 based on the divisibility rule?
Yes, 1822 is divisible by 911.
To check if 1822 is divisible by 911:
1. Multiply the last three digits by 3, 822 × 3 = 2466.
2. Subtract the result from the remaining digits excluding the last three, 1 – 2466 = -2465.
3. Since -2465 is not a direct multiple, check the full number: 1822 ÷ 911 = 2, confirming divisibility.
Check if 2733 follows the divisibility rule of 911.
No, 2733 is not divisible by 911.
To determine if 2733 is divisible by 911:
1. Multiply the last three digits by 3, 733 × 3 = 2199.
2. Subtract the result from the remaining digits excluding the last three, 2 – 2199 = -2197.
3. Since -2197 is not a multiple of 911, 2733 is not divisible by 911.
