If you take 3*7, you get 21. Bow you can take 21 times prime numbers until you get a 3 digit number. For example, 3*5*7=105. Therefore 105 will have factors of 3, 5 and 7.
The one digit number that has the same number of factors as the number six is three. Six's factors are 1, 2, 3, and 6 while three's factors are 1 and 3. Therefore, both numbers have the same number of factors.
The largest two-digit number that has exactly three factors is 99. A number has exactly three factors if it is the square of a prime number. In this case, ( 9 = 3^2 ) has three factors: 1, 3, and 9. However, since 99 is the largest two-digit number, we consider its factors, but it does not meet the criterion. The correct answer is 81, which is ( 9^2 ).
It is 105
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.
a 3 digit number that is divisible by on is a three digit number that is a multiple of one.
The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
9 has three factors: 1, 3, and 9
The one digit number that has the same number of factors as the number six is three. Six's factors are 1, 2, 3, and 6 while three's factors are 1 and 3. Therefore, both numbers have the same number of factors.
The largest two-digit number that has exactly three factors is 99. A number has exactly three factors if it is the square of a prime number. In this case, ( 9 = 3^2 ) has three factors: 1, 3, and 9. However, since 99 is the largest two-digit number, we consider its factors, but it does not meet the criterion. The correct answer is 81, which is ( 9^2 ).
It is 105
Using prime factorization, there are 2 three digit numbers with 9 factors: 512 and 768. There are no three digit numbers with 10 or more prime factors. 512=2^9 and 768=3*2^8
The only two-digit number that has three different prime factors is 2 x 3 x 5, which equals 30. This number has the prime factors 2, 3, and 5, all of which are distinct prime numbers. Any other two-digit number with three prime factors would have at least one repeated prime factor, making it not have three different prime factors.
144, 324, 576 and 900 are even three-digit square numbers that are multiples of 3.
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.
a 3 digit number that is divisible by on is a three digit number that is a multiple of one.
3 x 5 x 7 = 105
130, 260,390,520,650,780,910.1040. So the largest three digit number with factors of '5' & '13' is 910.
