What is the greatest product you can make using all the digits 1,2 3 4 ONCE?

If the investigation is extended to the five digits 1, 2, 3, 4, 5, then the largest product is given by: 431 x 52 = 22412.

How many three digits numbers can be formed using the digits 1,2 3 4 5 if digits can be repeated?

Total Number of Numbers which can be formed by numbers 1,2,3,4,5 (without repeating digitsi) = 5*4*3*2*! = 5! = 120.

How many even numbers greater than 300 can be formed with the digits 1,2 3 4 5 if repetition of digits in a number is not allowed?

111 even numbers
111 even numbers greater than 300 can be formed with the digits 1,2,3,4,5 if repetition of digits in a number is not allowed. Note: In questions like these, we have two categories in 3 digit numbers: Greater than 300 and less than 300.

How many even numbers greater than 2000 can be made from the integers 1,2 3 4 of each integer is used only once?

Since Zero is already used up, we are left with 1,2,3,4,5,6. Second digit can be any of these digits. Since repetition isn’t allowed, we cannot choose Zero here. So there are 6 options, to choose from, for second digit.

How many 5 prime numbers can be formed using digits 1 2 3 4 5 if the repetition of digits is not allowed?

Step-by-step explanation: Total numbers formed using 1, 2, 3, 4, and 5 without repetition is 5! = 120.

How many four digit numbers can be performed using each digit only?

Using digits 0,1,2,3,4,5 and 6 how many four digit numbers can be performed using each digit only once? For a 4 digit number, let’s consider 4 blank spaces. The first blank space can be filled by 1, 2, 3, 4, 5 or 6 (having 0 as the first digit will make the number 3-digit). So 6 possibilities for first place.

How many numbers can be used to fill the first place?

The first blank space can be filled by 1, 2, 3, 4, 5 or 6 (having 0 as the first digit will make the number 3-digit). So 6 possibilities for first place. Now there are 6 numbers possible for second place (can include 0 now).

How many 5-digit permutations are there of an integer greater than 5000?

Every sequence of the first five distinct digits forms the decimal representation of an integer greater than 10,000. Thus each such 5-digit permutation represents an integer greater than 5,000 . There are 5! such permutations.

What is the difference between 3rd and 4th digit?

Third digit can be from 1,2,3,4, 5 (5 possibilities) but not same as first and second digits. This means 5 – 2 = 3 possibilities ( n 7 = 3) Fourth digit can be from 1,2,3,4,5 (5 possibilities) but not same as first, second or third digits.
