Divisibility Rule of 787

The divisibility rule for 787 is a method by which we can find out if a number is divisible by 787 or not without using the division method. Check whether 1574 is divisible by 787 with the divisibility rule.

Step 1: Divide the number into groups of three digits from the right. Here, 1574 becomes 001 and 574.

Step 2: Subtract the second group from the first group. i.e., 001 - 574.

Step 3: If the result is divisible by 787 or equal to 0, then the number is divisible by 787. If the result from step 2 isn't divisible by 787, then the number isn't divisible by 787.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 787

.

Know the multiples of 787:

Memorize the multiples of 787 (787, 1574, 2361, 3148, etc.) to quickly check the divisibility.

Use negative numbers:

If the result after the subtraction is negative, consider it as positive for checking divisibility.

Repeat the process for large numbers:

Keep repeating the divisibility process until you reach a small number that is divisible by 787. For example: Check if 2361 is divisible by 787 using the divisibility test.

Divide into groups, 002 and 361. Subtract the second group from the first, 002 - 361 = -359. Consider the absolute value, 359 is not divisible by 787. Therefore, 2361 is not divisible by 787.

Use the division method to verify:

Use the division method to verify and crosscheck your results. This will help you confirm your findings.
