How does the divisibility rule for 4 and 8 work?
A number is a multiple of 4 if the last 2 digits are a multiple of 4 The 10s digit is even and the last digit is 0, 4 or 8 The 10s digit is odd and the last digit is 2 or 6 A number is a multiple of 8 if the last 3 digits are a multiple of 8 The 100s digit is even and the last 2 digits are a multiple of 8 The 100s digit is odd and the last 2 digits are 4 times an odd number
How many seven digit numbers are there when 0 and 4 cannot be the leading number?
If the number can contain repeated digits, the answer is 800000. Without repetition, there are 483840.
How many six digit numbers are there in which no digit is repeated even digits appeared in the even places and odd digits in the odd places and the number is divisible by 4?
There are 5760 such numbers.
How many four digit numbers can be formed from digits 1 2 3 4 if repeated is allowed and how many are odd numbers?
This is permutations with repetition. The answer is 4^4 = 256 total permutations. Since 2 of the digits used are odd (and 2 are even), then half of the possibilities will be odd: 128 odd numbers.
How many 4 digit numbers can be formed by the digits 1 2 3 4 5 6 7 if the numbers are odd?
4 x 6 x 5 x 4 = 480 if digits are not to be repeated. 4 x 73 = 1372 otherwise.

192 ways
How many 4 digit numbers can be formed from the digits 7341 if none of the digits can be repeated?

How many 4 digit numbers can you build if the number must be odd odd digits can be repeated and even digits cannot be repeated?
To form a 4-digit odd number, the last digit must be one of the odd digits (1, 3, 5, 7, 9), giving us 5 choices. For the first three digits, we can use odd digits freely (repeating allowed), giving us 5 choices for the first digit and 5 choices for the second digit. The third digit must be an even digit (0, 2, 4, 6, 8), but cannot repeat; therefore, we have 5 choices for the first digit and 4 choices for the second digit. Thus, the total number of valid 4-digit odd numbers is calculated as (5 \times 5 \times 5 \times 5 = 625).
How many 3 digit numbers can be made out of the numbers 1 2 3 and 4?
With repeated digits, 43 = 64 Without repeated digits, 4*3*2 = 24
How many 4 digit numbers can be formed from the digits 1234 if any of the digits are not repeated?
That would be 4! = 4 * 3 * 2 * 1 = 24
How many 4 digit numbers can be formed by the digits 3 4 6 if any of the digits can be repeated?
3*3*3*3=81
What is the greatest four-digit even number with no repeated digits?
The greatest 4-digit number with no repeated digits is... 9876
How many 4 digit numbers can be made from the digits 1 4 5 and 8?
Without repeating any of the digits: 4*3*2*1 = 24 If repeated digits are allowed, then 4*4*4*4 = 256
