Look at the product of the first 3 prime numbers: 2 x 3 x 5 = 30. Any number multiplied by 30 will have a 0 in the units digit. So, no matter how many prime numbers you are multiplying, if once you have a number ending in 0, all of the rest will end in 0.
Oh, dude, you want to know the unit's digits of the product of the first 21 prime numbers? Well, let me casually tell you that the unit's digit of a product depends on the unit's digits of the numbers being multiplied. Since the unit's digit of all prime numbers greater than 5 is either 1, 3, 7, or 9, the product of the first 21 prime numbers will end in a unit's digit that is a result of multiplying these digits together. Cool, right?
The product of the first three prime numbers (2, 3, and 5) is 30.
There are 21 two-digit prime numbers. The first two-digit prime number is 11, and the last two-digit prime number is 97. Prime numbers are numbers greater than 1 that are only divisible by 1 and themselves.
No, the product of two prime numbers is unique.
The first four prime numbers are 2, 3, 5, 7. The product of these numbers is 2 x 3 x 5 x 7 = 210
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.)
679 is the product of the largest single-digit prime number and the largest two-digit prime number.
non-prime no.

You had me until "product." The product of 4 digits can't be prime.
The first five two-digit prime numbers are 11, 13, 17, 19, and 23.
The ones digit in the product from multiplying the 305 prime numbers less than 2012 is 0 because the ones digit becomes 0 after 2 and 5 have been multiplied and remains unchanged after more prime numbers are multiplied.
It is 0. Two of the first 51 prime numbers are 2 and 5, whose product is 10. When you multiply 10 by any other whole numbers, the final digit (in the ones place value) will be 0.
The first three prime numbers containing the digit 7 are:7, 17, 37
The greatest two-digit prime number is 97. The lowest two-digit prime number is 11. The product of the two numbers is equal to 1067.
11 and 13.
The answer is vague but correct . Take any two prime numbers whose combined digit length is 501 and their product will generate a 500 or a 501 digit number.
