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 939.
The divisibility rule for 939 is a method by which we can find out if a number is divisible by 939 or not without using the division method. Check whether 1878 is divisible by 939 with the divisibility rule.
Step 1: Divide the number into three parts from the right, each having three digits. For 1878, we consider it as 001878.
Step 2: Separate the last three digits (878) and the rest (001).
Step 3: Multiply the last three digits by 1 and add it to the rest multiplied by 1 (as 1 is used for both parts in this case). 878 × 1 + 001 × 1 = 878 + 1 = 879.
Step 4: Check if 879 is divisible by 939. If yes, then the original number is divisible by 939.
Learning the divisibility rule helps kids master division. Let’s learn a few tips and tricks for the divisibility rule of 939.
Memorize the multiples of 939 (939, 1878, 2817...etc.) to quickly check divisibility. If the result from step 3 is a multiple of 939, then the number is divisible by 939.
If the result from step 3 is negative, ignore the negative sign and check the divisibility of the absolute value.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 939. For example, check if 3756 is divisible by 939 using the divisibility test. Separate the last three digits (756) and the rest (003). Multiply and add the parts: 756 × 1 + 003 × 1 = 756 + 3 = 759. Since 759 is not divisible by 939, 3756 is not divisible by 939.
Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
