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.
To find a two-digit number multiplied by a one-digit number to equal 378, we need to break down 378 into its prime factors: 2 x 3 x 3 x 3 x 7. The factors must be distributed between the two numbers. The closest combination is 18 x 21, which equals 378.
64
It is: 70
There are none but the smallest 3 digit number is 161
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.
The prime number between 20 and 30 whose ones digit is 7 greater than its tens digit is 23. The tens digit is 2, and the ones digit is 3, which is 7 greater than 2. Additionally, 23 is a prime number because it is only divisible by 1 and itself, with no other factors.
