What is the divisibility rule of 4 and 11?
For example, in the number 7480, the sum of digits at the odd position is 7 + 8, which is 15 and the sum of digits at the even position is 4 + 0, which is 4. The difference between 15 and 4 is 11. 11 can be completely divided by 11 with 0 as the remainder. Therefore, 7480 is divisible by 11.
Is 15 divisible by any number?
There is no one single rule for divisibility by 15, but every number that is divisible by 15 must be divisible by the factors of 15, namely 3 and 5. If your son knows these divisibility rules, then for divisibility by 15, he just includes both conditions. for divisibility by 5, the number must end in a 5 or a 0.
Which of the numbers are divisible by 11?
Consider the following numbers which are divisible by 11, using the test of divisibility by 11: (i) 154, (ii) 814, (iii) 957, (iv) 1023, (v) 1122, (vi) 1749, (vii) 53856, (viii) 592845, (ix) 5048593, (x) 98521258. -1 is divisible by 11. Hence, 154 is divisible by 11.
Which number is a divisible by 4?
A number is divisible by 4 if its last two digits are divisible by 4. For example, 780, 52, and 80,744 are divisible by 4, but 7,850 is not divisible by 4. To check whether a number is divisible by 4, just divide the last two digits of the number by 4.
How do you solve divisibility by 11?
Here an easy way to test for divisibility by 11. Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11.

How do you find the divisibility of 15?
A number is divisible by 15 if it is divisible by 5 (if the last digit is 5 or 0), and it is divisible by 3 (if sum of digits is divisible by 3).
Which of the given numbers is not divisible by 11?
Then, we know only 0 and multiples of 11 as 11, 22, 33 and so on will be divisible by 11. Now, we can clearly see only the number 888888 gives the number as 0 which is divisible by 11 and all other numbers are not divisible by 11. Therefore the total number of numbers which are not divisible by 11 are 6.
Which of the following is not divisible by 11?
Which of the following numbers are divisible by 4 572?
by 4: last two digits are 72 and 72 is divisible by 4. Therefore, 572 is also divisible by 4. by 8: last three digits are 572 and 572 is not divisible by 8. by 4: last two digits are 52 and 52 is divisible by 4.
Which is not divisible by 11?
Is the number 144 divisible by 4?
Example 1. Find whether the number 144 is divisible by 4. A number is divisible by 4 if the number is formed by its digits in ten’s place and units place is divisible by 4. In 144 the last 2 digits from the right side are 44 which is divisible by 4. Therefore 144 is also divisible by 4.
How do you know if a number is divisible by another?
