Divisibility Rule of 985

The divisibility rule for 985 is a method by which we can find out if a number is divisible by 985 or not without using the division method. Check whether 1970 is divisible by 985 with the divisibility rule.

Step 1: Identify the last three digits of the number, in 1970, the last three digits are 970.

Step 2: Check if these last three digits form a number that is divisible by 985.

Step 3: Since 970 is not divisible by 985, 1970 is not divisible by 985.

Learning divisibility rules will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 985.

Know the multiples of 985:

Memorize the multiples of 985 (985, 1970, 2955, etc.) to quickly check the divisibility. If the number formed by the last three digits is a multiple of 985, then the whole number is divisible by 985.

Use larger numbers:

When working with large numbers, break them into smaller parts or use known multiples to quickly ascertain divisibility.

Repeat the process for large numbers:

For very large numbers, break down the number into recognizable multiples of 985 and use the rule to determine divisibility.

Use the division method to verify:

Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
