Divisibility Rule of 745

The divisibility rule for 745 is a method by which we can determine if a number is divisible by 745 without using the division method.

Check whether 2235 is divisible by 745 using the divisibility rule.

Step 1: Since 745 is a composite number, break it down into its prime factors: 5, 149.

Step 2: Check divisibility by 5: The last digit of 2235 is 5, which is divisible by 5.

Step 3: Check divisibility by 149: We perform division or use any known rules for 149.

Since 2235 is not divisible by 149, it is not divisible by 745.

Learning the divisibility rule helps kids master division. Let’s learn a few tips and tricks for the divisibility rule of 745.

Know the multiples of 5 and 149:

Memorize the multiples of 5 and 149 to quickly check divisibility. If a number is not divisible by these individual factors, it is not divisible by 745.

Repeat the process for large numbers:

For larger numbers, repeat the process of checking divisibility by 5 and 149 individually until you reach a conclusion.

Use the division method to verify:

Students can use the division method to verify and cross-check their results. This will help them confirm their understanding.
