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 555.
The divisibility rule for 555 is a method by which we can find out if a number is divisible by 555 or not without using the division method. Check whether 1665 is divisible by 555 with the divisibility rule.
Step 1: Check if the number is divisible by 5. Since the last digit of 1665 is 5, it is divisible by 5.
Step 2: Check if the number is divisible by 3. Sum the digits: 1 + 6 + 6 + 5 = 18. Since 18 is divisible by 3, 1665 is divisible by 3.
Step 3: Check if the number is divisible by 37. Divide 1665 by 37. If it results in an integer, it is divisible by 37.
Since 1665 is divisible by 5, 3, and 37, it is divisible by 555.
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 555.
The divisibility rule of 555 helps us quickly check if a given number is divisible by 555, but common mistakes, like calculation errors, lead to incorrect results. Here, we will understand some common mistakes that will help you avoid them.
Is 2775 divisible by 555?
Yes, 2775 is divisible by 555.
To check if 2775 is divisible by 555, we can perform division directly or use a similar approach to check divisibility.
1) Notice that 555 is a multiple of 5, 37, and 3. First, check divisibility by 5: the last digit is 5, so it is divisible by 5.
2) Check divisibility by 37. Perform the division: 2775 ÷ 37 = 75, which is an integer.
3) Finally, check divisibility by 3. Sum the digits of 2775: 2 + 7 + 7 + 5 = 21, which is divisible by 3.
Since 2775 passes all individual checks, it is divisible by 555.
Check the divisibility rule of 555 for 1665.
Yes, 1665 is divisible by 555.
To check if 1665 is divisible by 555:
1) First, check divisibility by 5. The last digit is 5, so it is divisible by 5.
2) Next, check divisibility by 37. Perform the division: 1665 ÷ 37 = 45, which is an integer.
3) Finally, check divisibility by 3. Sum the digits of 1665: 1 + 6 + 6 + 5 = 18, which is divisible by 3.
Since 1665 passes all individual checks, it is divisible by 555.
Is -2220 divisible by 555?
No, -2220 is not divisible by 555.
To check if -2220 is divisible by 555, remove the negative sign and verify divisibility:
1) Check divisibility by 5. The last digit is 0, so it is divisible by 5.
2) Check divisibility by 37. Perform the division: 2220 ÷ 37 = 60, which is an integer.
3) Finally, check divisibility by 3. Sum the digits of 2220: 2 + 2 + 2 + 0 = 6, which is divisible by 3.
Despite passing individual checks, a miscalculation occurred; 2220 ÷ 555 is not an integer, so -2220 is not divisible by 555.
Can 110 be divisible by 555 following the divisibility rule?
No, 110 isn't divisible by 555.
To check if 110 is divisible by 555:
1) Check divisibility by 5. The last digit is 0, so it is divisible by 5.
2) Check divisibility by 37. Perform the division: 110 ÷ 37 ≈ 2.973, which is not an integer.
3) Check divisibility by 3. Sum the digits of 110: 1 + 1 + 0 = 2, which is not divisible by 3.
Since 110 fails the divisibility checks for 37 and 3, it is not divisible by 555.
Check the divisibility rule of 555 for 1110.
Yes, 1110 is divisible by 555.
To check the divisibility of 1110 by 555:
1) Check divisibility by 5. The last digit is 0, so it is divisible by 5.
2) Check divisibility by 37. Perform the division: 1110 ÷ 37 = 30, which is an integer.
3) Finally, check divisibility by 3. Sum the digits of 1110: 1 + 1 + 1 + 0 = 3, which is divisible by 3.
Since 1110 passes all individual checks, it is divisible by 555.
