number by 2,3 and 5
©
672​

Answer 1

Answer:

672 is divisible by 2

672 is divisible by 3

672 is not divisible by 5

Step-by-step explanation:

672 - unit digit is 2 which is even number so it is divisible by 2

672 - 6+7+2 =15 which is divisible by 3

672 - unit digit is 2 which is not divisible by 5 ( for divisible by 5 the unit digit must be 0 or 5)

Answer 2

Step-by-step explanation:

The Rule for 3: A number is divisible by 3 if the sum of the digits is divisible by 3. What does this mean? This means that we need to add up the digits in the number and see of the answer is can be divided by 3 without a remainder. Step 2: Determine if 3 divides evenly into the sum of 18.

A number is divisible by 2 if the last digit of the number is 0, 2, 4, 6, or 8. Example 1: Is the number 246 divisible by 2? Solution: Since the last digit of the number 246 ends in 6, that means it is divisible by 2.

Divisibility by 5 is easily determined by checking the last digit in the number (475), and seeing if it is either 0 or 5. If the last number is either 0 or 5, the entire number is divisible by 5. If the last digit in the number is 0, then the result will be the remaining digits multiplied by 2.
