If the 2 digit number is a multiple of both 5 and 7 then it is a multiple of (5 x 7) which equals 35. The only even 2 digit number which is a multiple of 35 is, 2 x 35 = 70
7 is.
Well honey, if you're looking for a 2-digit number multiplied by a 1-digit number to give you 378, you're out of luck. 378 is not divisible by any 1-digit number, so you might want to grab a calculator or brush up on your multiplication tables. Good luck with that math puzzle!

It is: 70
There are none but the smallest 3 digit number is 161
A two-digit number with exactly 7 factors must be of the form ( p^6 ), where ( p ) is a prime number, because the number of factors of ( n = p^e ) is ( e + 1 ). The only prime number that, when raised to the sixth power, results in a two-digit number is 2, since ( 2^6 = 64 ). Therefore, 64 is the only two-digit number that has exactly 7 factors.
As a product of its oprime factors: 2*5*7 = 70
The largest two-digit number with exactly three factors is 99. A number has exactly three factors if it is the square of a prime number, specifically in the form ( p^2 ) where ( p ) is a prime. The only prime number whose square is a two-digit number is 7, since ( 7^2 = 49 ) and ( 11^2 = 121 ) exceeds two digits. Thus, 49 is the largest two-digit number with exactly three factors.

The only 3-digit number that has factors of 2 and 7 is 14. Factors are numbers that can be multiplied to give the number in question. In this case, 2 x 7 = 14, making 14 the only 3-digit number with factors of 2 and 7.
The single-digit factors of 2100 are 1, 2, 3, 4, 5, 6, 7, 8, and 9. However, among these, the actual factors of 2100 are 1, 2, 3, 4, 5, 6, and 7. The number 8 and 9 are not factors of 2100. Thus, the complete list of single-digit factors is 1, 2, 3, 4, 5, 6, and 7.
2, 3, 5 and 7.
The highest four digit number with 13 and 7 as common factors is 9919, which is equal to 13 x 763 and 7 x 1417.
