Divisibility Rule of 802
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 802.
What is the Divisibility Rule of 802?
The divisibility rule for 802 is a method by which we can find out if a number is divisible by 802 or not without using the division method. Check whether 1604 is divisible by 802 with the divisibility rule.
Step 1: Divide the number into parts that can be easily handled. Here, consider 1604 as 1000+604.
Step 2: Check each part for divisibility by 802. Since 1000 and 604 are both not multiples of 802, combine them to see if their sum or subtraction results in a multiple of 802.
Step 3: After combining or using other mathematical adjustments, check if the adjusted number is a multiple of 802. If yes, then the number is divisible by 802. Otherwise, it is not.
Tips and Tricks for Divisibility Rule of 802
Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 802.
Break Down Large Numbers:
Break down large numbers into smaller parts that are easier to handle for checking divisibility.
Use Multiples of 802:
Memorize the multiples of 802 to quickly check divisibility. For instance, knowing that 802, 1604, 2406, etc., are multiples can be helpful.
Approximate and Adjust:
For large numbers, approximate to the nearest multiple of 802 and adjust to check for divisibility.
Use the Division Method to Verify:
Students can use the division method as a way to verify and cross-check their results. This will help them verify and also learn.

Divisibility Rule of 802 Examples
Problem 1
Can 2406 be divided evenly by 802?
Yes, 2406 is divisible by 802.
Explanation
To determine if 2406 is divisible by 802, we consider the rule:
1) Divide 2406 by 802.
2) The result is exactly 3, which is a whole number, so 2406 is divisible by 802 (802 × 3 = 2406).
Problem 2
Is 4812 divisible by 802?
No, 4812 is not divisible by 802.
Explanation
To verify divisibility of 4812 by 802:
1) Divide 4812 by 802.
2) The result is approximately 6.0, but not a whole number, indicating 4812 is not divisible by 802.
Problem 3
Check if 1604 is divisible by 802.
Yes, 1604 is divisible by 802.
Explanation
To verify divisibility of 1604 by 802:
1) Divide 1604 by 802.
2) The result is exactly 2, which is a whole number, so 1604 is divisible by 802 (802 × 2 = 1604).
Problem 4
Determine whether -1604 is divisible by 802.
Yes, -1604 is divisible by 802.
Explanation
To check divisibility of -1604 by 802:
1) Ignore the negative sign and perform the division 1604 ÷ 802.
2) The result is exactly 2, a whole number, so -1604 is divisible by 802 (802 × -2 = -1604).
Problem 5
Is 723 divisible by 802?
No, 723 is not divisible by 802.
Explanation
To determine if 723 is divisible by 802:
1) Divide 723 by 802.
2) The result is approximately 0.9, which is not a whole number, so 723 is not divisible by 802.
