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 161.
The divisibility rule for 161 is a method by which we can find out if a number is divisible by 161 or not without using the division method. Check whether 1936 is divisible by 161 with the divisibility rule.
Step 1: Find the difference between the number and the last two digits repeated twice. Here in 1936, the last two digits are 36. So, the number formed by repeating the last two digits is 3636.
Step 2: Subtract this number from the original number, i.e., 1936 - 3636 = -1700.
Step 3: Divide the result by 161. If the quotient is a whole number, then the number is divisible by 161. Since -1700 divided by 161 is not a whole number, 1936 is not divisible by 161.
Learn divisibility rules to help master division. Let’s learn a few tips and tricks for the divisibility rule of 161.
The divisibility rule of 161 helps us quickly check if a given number is divisible by 161, but common mistakes can lead to incorrect conclusions. Here are some common mistakes and solutions:
Is 483 divisible by 161?
No, 483 is not divisible by 161.
To check if 483 is divisible by 161, we can try dividing directly. 483 ÷ 161 ≈ 3.00, which is not an integer, so 483 is not divisible by 161.
Can 1610 be divisible by 161?
Yes, 1610 is divisible by 161.
1610 ÷ 161 = 10, which is an integer. Therefore, 1610 is divisible by 161.
Determine if 322 is divisible by 161.
Yes, 322 is divisible by 161.
Direct division shows that 322 ÷ 161 = 2, which is an integer. Hence, 322 is divisible by 161.
Is 805 divisible by 161?
No, 805 is not divisible by 161.
By dividing 805 by 161, we get 805 ÷ 161 ≈ 5.00, which is not an integer. Therefore, 805 is not divisible by 161.
Evaluate if 16100 is divisible by 161.
Yes, 16100 is divisible by 161.
Dividing 16100 by 161 results in 16100 ÷ 161 = 100, which is an integer. Thus, 16100 is divisible by 161.
