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 938.
The divisibility rule for 938 helps us determine if a number is divisible by 938 without performing division. To check whether a number like 1876 is divisible by 938 using this rule, follow these steps:
Step 1: Divide the number into groups, each containing three digits starting from the end. For 1876, we have the groups: 876 and 1.
Step 2: Multiply the number in the group with the least significant digits by 938. Here, 876 × 938 = 821088.
Step 3: Subtract the result from Step 2 with the number formed by the remaining groups. Here, subtract 821088 from 1: 1 - 821088 = -821087.
Step 4: If the result is 0 or a multiple of 938, then the original number is divisible by 938.
Learning the divisibility rule can help kids master division. Here are a few tips and tricks for the divisibility rule of 938:
Memorize the multiples of 938 (938, 1876, 2814, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 938, then the number is divisible by 938.
If the result we get after subtraction is negative, consider it as positive for checking the divisibility of a number.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 938. For example, check if 1876000 is divisible by 938 using the divisibility test. Divide into groups: 000 and 1876, then multiply 000 by 938 = 0. Subtract from 1876: 1876 - 0 = 1876. Since 1876 is a multiple of 938, 1876000 is divisible by 938.
Students can use the division method to verify and cross-check their results. This will help them verify and also learn.
