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.)

89 x 90 = 8010 which are two consecutive two digit numbers that equal 8010.

Its 28 and 29.

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.

two consecutive 4- digit numbers have a sum of 9173.what are the numbers?

28 and 29

It is: 66*67 = 4422

The numbers are 28 and 29.

In order to have a product, you must have a multiplication problem which requires two numbers to be multiplied. For example, in 2 * 3 = 6, 6 is the product.

Zero. Any five consecutive natural numbers will contain at least one multiple of 2 and at least one multiple of 5, meaning that the product will be a multiple of 10.

what is the unit digit of the product if hundred 7"s r multiplied

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.

As the numbers 1 to 99 are multiplied together, one factor of the product will be 10 which means the last digit must be 0 (a zero). Without working out the product, it can be seen that every multiple of 5 in the original numbers can be paired up with an even number (that is not a multiple of five) and multiplied together (which produces a multiple of 10) which are all factors of the product together; thus the product will ends with that number of zeros: there are 19 multiples of 5 in the numbers 1-99, so the last 19 digits of the product are all 0 (zero).

There are four consecutive 3-digit numbers with a sum of 2,494: 622, 623, 624 and 625.

0 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.
