How many 3 digit numbers are there such that the product of its digits is equal to the square of the sum of the digits?

The digits of each of the above two 5-factor products can be arranged in 5!/3! = 120/6 = 20 ways to make the product of 1000. Therefore, 2*20 = 40 such products of the digits are possible.

How many three digit numbers are there such that the product?

The product of the digits of the three-digit numbers should be more than 2 and less than 7 . Hence the possible numbers are as follows. Hence there are a total of 21 possibilities.

How many 3 digit numbers are possible such that the product of their digits is a natural number less than or equal to 9?

There are 44 three digit numbers such that the product of the digits is a natural number less than or equal to 9.

How many 3 digits numbers are there for which the product of their digits is more than 2 but less than 7?

21 digits
∴ There are 21 digits whose products of their digits is more than 2 but less than 7.

What is the least number of digits in the number formed from only zeros and ones?

Out of natural numbers, the answer is trivially 0. So trivially that clearly you actually care about positive integers instead. Out of those, the answer is 11111111100 (nine ones and then two zeros).

How many digits in all are required to write numbers from 1 to 60?

Answer: So we have , in total, 1×9+2×90+3×1=9+ 180+3=192 digits.

How many three-digit numbers are there in all?

In the tens place and the one’s place, there can be any digit from 0-9. There is a possibility of 10 digits in the hundredth place and 10 digits in the unit’s place. Thus, there are 9 × 10 × 10 = 900 three-digit numbers in all. Therefore there are 900 three-digit numbers in all.

How to find the product of the digits of a number?

Given a number, the task is to find the product of the digits of a number. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Get the rightmost digit of the number with help of remainder ‘\%’ operator by dividing it with 10 and multiply it with product.

What is the smallest 3-digit number that can start with 0?

100 is the smallest 3-digit number and 999 is the greatest 3 digit number. A 3-digit number cannot start with 0. 10 tens make 1 hundred which is the smallest 3 digit number and 10 hundred make a thousand which is the smallest 4 digit…

What is the largest and smallest 3-digit number in the table?

Using the digits 7, 3, and 6, the largest number is 763 (digits in descending order) and the smallest number is 367 (digits in ascending order). Using the digits 4, 0, and 8, the largest number will be 840 but the smallest 3-digit number is 408 and not 048. Download FREE Study Materials Download FREE Concept E-book
