What 3 digit numbers are diviseable by 7 with no remainder using the digits 8 6 and 1 once each?
168 and 861.
How many 3 digit numbers can you make using the numbers 6 7and 8 if the digits can be repeated?
If you only use each digit once the number is 6 (it is a simple permutation and 3!=6). If you can repeat the digits there are 9 possible 3-digit numbers that start with 6, 9 that start with 7, and 9 that start with 8, giving you 27 possibilities.
How many 4 digit numbers can be formed using the digits 1 3 5 7 9?
Using only the numbers 1,3,5,7,9, and using each number only once, we have 5 options for the first digit, then 4 remaining options for the second, 3 remaining options for the third and 2 remaining options for the fourth. This means there are 5x4x3x2 ways to combine the digits 1,3,5,7,9 into a 4 digit number. 5x4x3x2=120, so there are 120 four digit numbers that can be made.
How many 2-digit or 3-digit numbers can be formed using the digits 134568 and 9 which are diisible by 4?
48. Assuming no digit can be used more than once, the two digit numbers divisible by 4 are: 16, 36, 48, 56, 64, 68, 84, 96 8 of them. For any number to be divisible by 4, only the last two digits need be divisible by 4; so for three digit numbers, each of the two digit numbers above can be preceded by any of the remaining 5 digits and still be divisible by 4. → 5 x 8 = 40 three digit numbers are divisible by 4 → 40 + 8 = 48 two or three digit numbers made up of the digits {1, 3, 4, 5, 6, 8, 9} are divisible by 4. If repeats are allowed, there are an extra 2 two digit numbers (44 and 88) and each of the two digit numbers can be preceded by any of the 7 digits, making a total of 7 x 10 + 10 = 80 two and three digits numbers divisible by 4 make up of digits from the given set.
How many 3-digit numbers can be made using the digits 1 5 7 4 6 if you can only use each digit once in ever number?
You have 5 choices for the 1st digit of the number. 4 choices for the 2nd digit and 3 choices for the 3rd and final digit. This means that there are 5 x 4 x 3 = 60 3-digit numbers that can be made from 5 different digits subject to each digit only being used once.
How many 4 digit numbers can be formed by the digits 1 2 3 4 using each digit only once?
24 different numbers.
How many 4 digit numbers have 6 as their second digit?
There are 9 digits that can be the first digit (1-9); for each of these there is 1 digit that can be the second digit (6); for each of these there are 10 digits that can be the third digit (0-9); for each of these there are 10 digits that can be the fourth digit (0-9). → number of numbers is 9 × 1 × 10 × 10 = 900 such numbers.
How many different numbers can you make with the digits 1 2 3 and 4 using each digit only once?
If you want 4-digit numbers, there are 24 of them.
How many 4 digit numbers can be formed from digits 123456789?
There are 7,290 different 4-digit numbers that can be formed from the digits 1-9 without repetition.
How many even four digit numbers can be made using 02356 where the first digit is cannot be 0 and no digits are repeated?
Assuming that 2356 is a different number to 2365, then: 1st digit can be one of four digits (2356) For each of these 4 first digits, there are 3 of those digits, plus the zero, meaning 4 possible digits for the 2nd digit For each of those first two digits, there is a choice of 3 digits for the 3rd digit For each of those first 3 digits, there is a choice of 2 digits for the 4tj digit. Thus there are 4 x 4 x 3 x 2 = 96 different possible 4 digit numbers that do not stat with 0 FM the digits 02356.
How many 4-digit numbers can be formed by the digits 01 2 3 456789 using the digits more than once in each number example 1112 1122?
Four digit numbers span from 1000 to 9999. This totals (9999-1000) +1 = 9000 different four digit numbers
What 3 digit numbers are diviseable by 7 with no remainder using the digits 8 6 and 1 once each?
168 and 861.
How many four digit numbers can you make using the digits 1234 and the 2 and 3 must be next to each other?
Twelve of them.
What is the sum of the greatest and smallest four digit numbers formed by using each of d digits 6039 atleast once?
9630
How many 3 digit numbers can be formed using the digits 1 to 7?
If they can be repeated, 343 different numbers. If they can be used once each, there are only 210.
What 5 digit number has Numbers increasing from the left Each digit is different 1st and 5th digits are square numbers 1st and 4th digits are cubed numbers 2nd 3rd digits are even?
12689 14689 12489
How many 4-digit numbers can you write using 3 and 4?
For each number, there are four digits, and for each digit, there are two possibilities for digits: 3 or 4. So the number of 4-digit numbers is 2*2*2*2 = 16. The 4-digit numbers using 3 and 4 are: 3333 3334 3343 3344 3433 3434 3443 3444 4333 4334 4343 4344 4433 4434 4443 4444
