What one-digit number is the product of two consecutive prime numbers?
There are only two prime numbers that are consecutive numbers, 2 and 3. Their product is 2 x 3 = 6. The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)
How many 5 digit numbers are there?
There are 9000 of them.
Find 5 four digit numbers such that the product of the digits of each four digit prime number are also prime?
You had me until "product." The product of 4 digits can't be prime.
How many 5-digit numbers have digits whose product is equal to 4?
There are 15 of them.
What is the last digit in the product of the first 20 odd natural numbers?
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
How many 5 digit numbers are divisible by 150?
There are 600 5-digit numbers divisible by 150.
What one-digit number is the product of two consecutive prime numbers?

The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)
How many two-digit numbers has a digit sum equal to 5?
There are five such numbers.
How many 5 digit numbers are even?
With a total of 90,000 five digit numbers, we can conclude that there is 45,000 EVEN five digit numbers.
How many 5 digit numbers are there?

How many 3-d How many 3-digit numbers will be there which are divisible by 19igit numbers with atleast one 5 in their digits?
None. 3 digit numbers are not divisible by 19 digit numbers.
How many 5 digits are there?
There are 90000 5-digit numbers.
How many 3-digit numbers are there using 2 4 6 8 and 9?
There are 5 numbers which can make the 3 digit numbers in this example. Therefore each digit in the 3 digit number has 5 choices of which number can be placed there. Therefore number of 3 digit numbers = 5 x 5 x 5 = 125
