How many 3 digit positive integers have 5 as the product of their digits?
Three of them.
How many three-digit positive integers have digits whose product is 24?
To find the number of three-digit positive integers with digits whose product is 24, we can break down 24 into its prime factors: 2 x 2 x 2 x 3. The possible combinations for the three digits are (2, 2, 6), (2, 3, 4), and (2, 4, 3). These can be arranged in 3! ways each, giving a total of 3 x 3! = 18 three-digit positive integers.
What is the sum of all the positive two-digit integers where one of the digits is three times the other?
31 + 62 + 93 + 13 + 26 + 39 = 264
How many three-digit counting numbers are not multiples of 5?
There are 720 of them.
How many three digit integers are exactly 17 more than a two digits integers?
17
How many positive three digit integers are multiples of 85?
10 of them.
How many positive three-digit integers are divisible by neither 2 or 3?
the range of three-digit integers is from 100 to 999. Therefore, there are 300 positive three-digit integers that are divisible by neither 2 nor 3.1 day ago
How many 3 digit positive integers have 5 as the product of their digits?
Three of them.
What is the largest three-digit number with exactly two factors that are positive integers?
997
How many positive integers with exactly three decimal digit positive integers between 100 and 999 inclusive divisible by 7?
Of the 729 numbers that satisfy the requirement of positive integers, 104 are divisible by 7.
How many three digit positive integers are square numbers?
102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.
How many three-digit positive integers have digits whose product is 24?
To find the number of three-digit positive integers with digits whose product is 24, we can break down 24 into its prime factors: 2 x 2 x 2 x 3. The possible combinations for the three digits are (2, 2, 6), (2, 3, 4), and (2, 4, 3). These can be arranged in 3! ways each, giving a total of 3 x 3! = 18 three-digit positive integers.
What are three number that have 2 4 and 8 as a factor and what these number have in common?
Any multiple of 24 has 2, 3 and 8 as factors which are all positive single-digit integers.
How many three digit counting numbers are multiples of 2 but not of 55?
There are 898 three-digit even numbers. Nine of them are multiples of 55. That leaves 889 * * * * * There are 450 three-digit even numbers and 17 of them are multiples of 55. So that leaves 433.
What are the three categories of integers?
The set of integers is divided into three subsets. One is the positive integers. Another is the negative integers. The last subset has one element -- zero. In sum, integers are composed of the positive integers, the negative integers, and zero.
What are three positive integers whose sum equals their product?
The first three positive integers, 1, 2, and 3, satisfy this condition.
What is the sum of all the positive two-digit integers where one of the digits is three times the other?
31 + 62 + 93 + 13 + 26 + 39 = 264
