What is the largest 3 digit number with exactly five prime factors?
The best way to tackle this is to take the largest 3 digit number (999) and work out its prime factors. You can then work down until you get one with exactly five prime factors. 999 is 3x3x3x37, 998 is 2x499, 997 is prime, 996 is 2x2x3x83, 995 is 5x199, 994 is 2x7x71, 993 is 3x331, 992 is 2x2x2x2x2x31, 991 is prime, 990 is 2x3x3x5x11. That is the first we came across with five prime factors. Therefore the largest 3 digit number with exactly five prime factors is 990.
What numbers have exactly five factors?
A number with exactly five factors is a number that is a prime number raised to the fourth power (p4). The factors are 1, p, p2, p3, and p4. Examples: The 5 factors of 24 = 16 are 1, 2, 4, 8, and 16. The 5 factors of 34 = 81 are 1, 3, 9, 27, and 81. The 5 factors of 54 = 625 are 1, 5, 25, 125, and 625.
What is the least number with exactly 8 factors?
The smallest number with exactly eight factors is 24.
What numbers have exactly five factors that are over 100?
A number with exactly five factors is a number that is a prime number raised to the fourth power (p4). The factors are 1, p, p2, p3, and p4. Example: The 5 factors of 54 = 625 are 1, 5, 25, 125, and 625. The 5 factors of 74 = 2401 are 1, 7, 49, 343, and 2401. The 5 factors of 114 = 14641 are 1, 11, 121, 1331, and 14,641.
