The numbers that are divisible by four are infinite. Five of them are: 4, 8, 12, 16, 20.
Even numbers are numbers that are evenly divisible by 2. The first five even numbers would be 2, 4, 6, 8, and 10.
The numbers that are divisible by two are infinite. The first four are: 2, 4, 6, 8.
A five-digit number that is divisible by both 9 and 4 must meet the criteria for divisibility by these numbers. A number is divisible by 9 if the sum of its digits is divisible by 9, and it is divisible by 4 if the last two digits form a number that is divisible by 4. The smallest five-digit number is 10,000, and the largest is 99,999; thus, any five-digit number that meets these criteria can be calculated by finding the least common multiple of 9 and 4, which is 36, and checking multiples of 36 within that range. For example, 10,008 is a five-digit number divisible by both 9 and 4.
The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.
To find the numbers between 1 and 100 inclusive that are divisible by either 9 or 4, we first determine how many numbers are divisible by 9 and how many are divisible by 4. There are 11 numbers divisible by 9 (9, 18, 27, ..., 99) and 25 numbers divisible by 4 (4, 8, 12, ..., 100). However, we must be careful not to double-count numbers divisible by both 9 and 4 (36, 72). Therefore, the total number of numbers divisible by 9 or 4 between 1 and 100 inclusive is 11 + 25 - 2 = 34.
If you had tried the first such set you would have seen that the answer is no. 1+2+3+4 = 10 which is not divisible by 4.
All 4 digit numbers that are divisible by 9 are also divisible by 3. The first is 1008 and the last is 9999.
numbers that are divisible by 4 is either: 4n or numbers in which the number formed by last two digits are divisible by 4
4
No. If the last two numbers are not divisible by 4, then the number is not divisible by 4.
