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 things. In this topic, we will learn about the divisibility rule of 387.
The divisibility rule for 387 is a method by which we can find out if a number is divisible by 387 or not without using the division method. Check whether 1161 is divisible by 387 using the divisibility rule.
Step 1: Divide the number into groups of three digits from the right. Here, 1161 becomes 1 and 161.
Step 2: Multiply the first group (rightmost) by 1, the second by -2, the third by 3, and so on in alternating pattern. Calculate: 161 × 1 = 161 and 1 × (-2) = -2.
Step 3: Add these results: 161 + (-2) = 159.
Step 4: Verify if 159 is a multiple of 387. Since it is not, 1161 is not divisible by 387.
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 387.
The divisibility rule of 387 helps us quickly check if a number is divisible by 387, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Is 774 divisible by 387?
Yes, 774 is divisible by 387.
To check if 774 is divisible by 387, we can directly divide 774 by 387. 774 ÷ 387 = 2, which is an integer, so 774 is divisible by 387.
Check the divisibility rule of 387 for 1161.
Yes, 1161 is divisible by 387.
To confirm divisibility, divide 1161 by 387. 1161 ÷ 387 = 3, which is an integer, indicating that 1161 is divisible by 387.
Is 1551 divisible by 387?
No, 1551 is not divisible by 387.
When you divide 1551 by 387, the result is 4.00775, which is not an integer. Therefore, 1551 is not divisible by 387.
Can 2322 be divisible by 387 following the divisibility rule?
Yes, 2322 is divisible by 387.
For checking, divide 2322 by 387. 2322 ÷ 387 = 6, which is an integer. Thus, 2322 is divisible by 387.
Check the divisibility rule of 387 for 1935.
No, 1935 is not divisible by 387.
Dividing 1935 by 387 gives approximately 5.0, which is not an exact integer. Hence, 1935 is not divisible by 387.
