## What are the numbers that are divisible by 10?

A number is divisible by 10 if the last digit of the number is 0. The numbers 20, 40, 50, 170, and 990 are all divisible by 10 because their last digit is zero, 0. On the other hand, 21, 34, 127, and 468 are not divisible by 10 since they don’t end with zero.

## Which number is divisible by all numbers from 1 to 10?

2520

2520 is: the smallest number divisible by all integers from 1 to 10, i.e., it is their least common multiple.

**How many numbers from 1 to 100 are there each of which is exactly divisible by 6?**

16 Numbers are divisible by 6 which lies 1 to 100.

**What does a number have to end in to be divisible by 10?**

The Rule for 10: Numbers that are divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. Basically, this means that for a number to be divisible by 10, the last digit must be a 0. Take a look at the last digit: 23,890.

### How do you know if a number is divisible by 1 10?

A number is divisible by 10, if last digit is 0. Example: 20 is divisible by 10 as last digit is 0.

### How do you find the smallest number divisible by 1 10?

2520 is the smallest number that can exactly be divided by all integers (whole numbers) from 1 to 10, whether even or odd. It also happens to be divisible by 12, but not 11. The secret of the number 2520 is hidden in the multiplication of [7 × 30 × 12].

**What is the least number that is divisible by all the numbers from 1 to 10 both inclusive?**

Hence 2520 is the least number that is divisible by all the numbers between 1 and 10 (both inclusive)

**What is the least number that is divisible by all the numbers from 1 to 10 both including?**

2520. Hint: To find out the least number divisible by all the numbers from 1 to 10 which we need to find out the Least Common Multiple of all the numbers from 1 to 10.

#### How many such numbers are there between 1 & 100 such that each of which is not divisible by 4 and has one digit as 4 in the number?

∴ The required numbers are 4, 24, 40, 44, 48, 64, 84. Clearly, there are 7 such numbers.

#### What is the sum of the numbers between 1 and 100 which are divisible by?

Hence, we have obtained the sum of integers from 1 to 100 which are divisible by 2 or 5 as 3050.

**What is the divisibility rule for 100?**

A number is divisible by 100 if it ends in “00”. For example, 450,000 is divisible by 100. A number is divisible by 1000 if it ends in “000”.
