The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. In real life, we can use divisibility rules for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 437
The divisibility rule for 437 is a method to determine if a number is divisible by 437 without using the division method. Let’s check whether 873474 is divisible by 437 using the divisibility rule.
Step 1: Split the number into groups of three digits from the right. For 873474, we have two groups: 474 and 873.
Step 2: Multiply the last group by 2, so 474 × 2 = 948.
Step 3: Subtract the result from Step 2 from the next group. So, 873 - 948 = -75.
Step 4: If the result from Step 3 is a multiple of 437 or zero, the number is divisible by 437. Here, -75 is not a multiple of 437, so 873474 is not divisible by 437.
Learn the divisibility rule to master division. Let’s learn a few tips and tricks for the divisibility rule of 437.
Memorize the multiples of 437 (437, 874, 1311, 1748…etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 437, the number is divisible by 437.
If the result we get after the subtraction is negative, consider it as positive for checking divisibility.
Students should repeat the divisibility process until they reach a small number that is divisible by 437.
Students can use the division method to verify and crosscheck their results. This will help them to verify and also learn.
The divisibility rule of 437 helps us quickly check if a given number is divisible by 437, but common mistakes like calculation errors can lead to incorrect results. Here, we will understand some common mistakes and how to avoid them.
Yes, 1748 is divisible by 437.
To determine if 1748 is divisible by 437, we apply the divisibility rule:
1) Multiply the last digit of the number by 3, 8 × 3 = 24.
2) Subtract the result from the remaining digits, excluding the last digit, 174 – 24 = 150.
3) Check if 150 is a multiple of 437. Since 150 isn't a multiple of 437, return to step 1 with 150.
4) Multiply the last digit of 150 by 3, 0 × 3 = 0.
5) Subtract the result from the remaining digits, excluding the last digit, 15 – 0 = 15.
6) Check if 15 is a multiple of 437. No, continue the steps.
7) Since we have no more steps to reduce further and 15 is not a multiple of 437, this process reveals that our approach needs adjustment. Recalculate 1748 directly, 1748 ÷ 437 = 4 which is an integer, confirming divisibility.
Check the divisibility rule of 437 for 2185.
Yes, 2185 is divisible by 437.
To verify if 2185 is divisible by 437, we use the steps:
1) Multiply the last digit of the number by 3, 5 × 3 = 15.
2) Subtract the result from the remaining digits, excluding the last digit, 218 – 15 = 203.
3) Check if 203 is a multiple of 437. Since 203 is not a multiple, repeat the steps.
4) Multiply the last digit of 203 by 3, 3 × 3 = 9.
5) Subtract the result from the remaining digits, excluding the last digit, 20 – 9 = 11.
6) 11 is not a multiple of 437; however, checking directly, 2185 ÷ 437 = 5 which is a whole number, confirming divisibility.
Is -874 divisible by 437?
Yes, -874 is divisible by 437.
To check if -874 is divisible by 437, disregard the negative sign:
1) Multiply the last digit of 874 by 3, 4 × 3 = 12.
2) Subtract the result from the remaining digits, excluding the last digit, 87 – 12 = 75.
3) Check if 75 is a multiple of 437. No, continue reducing.
4) Multiply the last digit of 75 by 3, 5 × 3 = 15.
5) Subtract the result from the remaining digits, excluding the last digit, 7 – 15 = -8.
6) -8 is not a multiple of 437, but directly check 874 ÷ 437 = 2, confirming it is divisible.
Can 523 be divisible by 437 following the divisibility rule?
No, 523 isn't divisible by 437.
To verify if 523 is divisible by 437:
1) Multiply the last digit by 3, 3 × 3 = 9.
2) Subtract the result from the remaining digits, excluding the last digit, 52 – 9 = 43.
3) Check if 43 is a multiple of 437. Since 43 is not a multiple of 437 and the number cannot be reduced further, 523 is not divisible by 437.
Check the divisibility rule of 437 for 1311.
No, 1311 is not divisible by 437.
To see if 1311 is divisible by 437, apply the steps:
1) Multiply the last digit by 3, 1 × 3 = 3.
2) Subtract the result from the remaining digits, excluding the last digit, 131 – 3 = 128.
3) Check if 128 is a multiple of 437. No, continue.
4) Multiply the last digit of 128 by 3, 8 × 3 = 24.
5) Subtract the result from the remaining digits, excluding the last digit, 12 – 24 = -12.
6) Since -12 is not a multiple of 437 and can't be reduced further, 1311 is not divisible by 437.
