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 the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 145.
The divisibility rule for 145 is a method by which we can find out if a number is divisible by 145 or not without using the division method. Check whether 4355 is divisible by 145 with the divisibility rule.
Step 1: Separate the last two digits of the number, here in 4355, 55 is the last two digits.
Step 2: Multiply the rest of the number by 3, i.e., 43 × 3 = 129.
Step 3: Add the result from Step 2 to the last two digits. i.e., 129 + 55 = 184.
Step 4: As it is shown that 184 is not a multiple of 145, the number is not divisible by 145. If the result from step 3 is a multiple of 145, then the number is divisible by 145.
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 145.
The divisibility rule of 145 helps us quickly check if a given number is divisible by 145, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes that will help you to understand.
Is the number 2900 divisible by 145?
Yes, 2900 is divisible by 145.
To check if 2900 is divisible by 145, use the divisibility rule for 145.
1) Divide the number by 5 first, as 145 ends in 5. 2900 ÷ 5 = 580.
2) Check if 580 is divisible by 29 (since 145 = 5 × 29).
3) 580 ÷ 29 = 20, which is an integer. Therefore, 2900 is divisible by 145.
Can the number 725 be divided evenly by 145?
No, 725 is not divisible by 145.
To determine if 725 is divisible by 145, apply the divisibility rule:
1) Divide 725 by 5, since the last digit is 5. 725 ÷ 5 = 145.
2) Check if 145 is divisible by 29. 145 ÷ 29 = 5, which is an integer.
3) However, the initial division by 5 should also be checked for further divisibility by 29, and the result of 145 is already a multiple of 145 without further division required. In this context, it's confirmatory that 725 is exactly divisible by 145 when broken down correctly.
Is -1015 divisible by 145?
No, -1015 is not divisible by 145.
To check the divisibility of -1015:
1) Remove the negative sign and divide 1015 by 5. 1015 ÷ 5 = 203.
2) Check if 203 is divisible by 29. 203 ÷ 29 ≈ 7, which is not an integer.
3) Therefore, 1015 is not divisible by 145.
Verify if 4350 is divisible by 145.
Yes, 4350 is divisible by 145.
To verify divisibility:
1) Divide 4350 by 5. 4350 ÷ 5 = 870.
2) Check if 870 is divisible by 29. 870 ÷ 29 = 30, which is an integer.
3) Since both checks are satisfied, 4350 is divisible by 145.
Determine if 5800 is divisible by 145.
Yes, 5800 is divisible by 145.
To determine divisibility:
1) Divide 5800 by 5. 5800 ÷ 5 = 1160.
2) Check if 1160 is divisible by 29. 1160 ÷ 29 = 40, which is an integer.
3) Therefore, 5800 is divisible by 145.
