The divisibility rule is a way to find out 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 280.
The divisibility rule for 280 is a method by which we can find out if a number is divisible by 280 or not without using the division method. Check whether 5600 is divisible by 280 with the divisibility rule.
Step 1: Check if the number is divisible by 10. Since 5600 ends in 0, it is divisible by 10.
Step 2: Divide the number by 10 to get 560. Now check if 560 is divisible by 28 (since 280 = 28 × 10).
Step 3: Check if 560 is divisible by 28. You can do this by dividing 560 by 28, which gives a whole number (20), indicating that 560 is divisible by 28.
Step 4: Since 560 is divisible by 28, the original number, 5600, is divisible by 280.
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 280.
The divisibility rule of 280 helps us to quickly check if a number is divisible by 280, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Is 1960 divisible by 280?
Yes, 1960 is divisible by 280.
To check if 1960 is divisible by 280, use the following approach:
1) Verify if 1960 is divisible by 10, as 280 ends in a zero. Yes, it is, since it ends in a zero.
2) Next, divide 196 by 28 (since 280 divided by 10 is 28).
3) 196 divided by 28 equals 7, which is a whole number.
Since both conditions are met, 1960 is divisible by 280.
Check whether 2240 is divisible by 280.
Yes, 2240 is divisible by 280.
To apply the divisibility rule for 280 on 2240:
1) Check if 2240 is divisible by 10, which is true since it ends in a zero.
2) Now, divide 224 by 28 (because 280 divided by 10 is 28).
3) 224 divided by 28 equals 8, a whole number.
Thus, 2240 is divisible by 280.
Is 1400 divisible by 280?
Yes, 1400 is divisible by 280.
For checking divisibility of 1400 by 280:
1) Confirm that 1400 is divisible by 10, which it is, since it ends in zero.
2) Divide 140 by 28 (because 280 divided by 10 is 28).
3) 140 divided by 28 equals 5, a whole number.
Therefore, 1400 is divisible by 280.
Can 2530 be divisible by 280 according to the divisibility rule?
No, 2530 is not divisible by 280.
To check divisibility of 2530 by 280:
1) Verify if 2530 is divisible by 10, which it is.
2) Divide 253 by 28 (since 280 divided by 10 is 28).
3) 253 divided by 28 equals approximately 9.0357, not a whole number.
So, 2530 is not divisible by 280.
Check the divisibility rule of 280 for 3360.
Yes, 3360 is divisible by 280.
To determine if 3360 follows the divisibility rule for 280:
1) Confirm that 3360 is divisible by 10, which it is.
2) Divide 336 by 28 (as 280 divided by 10 is 28).
3) 336 divided by 28 equals 12, a whole number.
Hence, 3360 is divisible by 280.
