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 485.

What is the Divisibility Rule of 485?

The divisibility rule for 485 is a method by which we can find out if a number is divisible by 485 or not without using the division method. Check whether 970 is divisible by 485 with the divisibility rule.

Step 1: Break down 485 into its prime factors, which are 5, 97, and 1.

Step 2: Check if the number is divisible by each of these factors.

Example: 970 is divisible by 5 because it ends in 0. Then check 970 ÷ 97, which does not result in an integer.

Step 3: Since 970 is not divisible by 97, it is not divisible by 485.

Tips and Tricks for Divisibility Rule of 485

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 485.
 

  • Know the multiples of 485: Memorize the multiples of 485 (485, 970, 1455, etc.) to quickly check divisibility.
     
  • Use prime factorization: Knowing the factors can help you quickly determine divisibility by checking smaller calculations.
     
  • Repeat the process for large numbers: For large numbers, break them down and check against each factor to ensure 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.

Problem 2

Check if 2425 is divisible by 485.

Okay, lets begin

No, 2425 is not divisible by 485. 

Explanation

To determine if 2425 is divisible by 485, follow these steps:  

1) Check if the number is a multiple of 5, which it is, since it ends in 5.  

2) Divide 2425 by 485 to see if the quotient is an integer: 2425 ÷ 485 ≈ 5.

Problem 4

Can 1455 be divisible by 485?

Okay, lets begin

No, 1455 isn't divisible by 485.

Explanation

To check if 1455 is divisible by 485, follow these steps:  

1) Divide 1455 by 485: 1455 ÷ 485 = 3.

  2) The quotient is an integer, but to confirm, multiply back: 485 x 3 = 1455.  

3) Since the multiplication confirms the division, 1455 is actually divisible by 485, correcting the initial answer.
