30 has exactly 8 factors 1,2,3,5,6,10,15,30
7 is a prime number, and not a factor of 8 or 9. 1, 2, 4, and 8 are factors of 8. 1, 3, and 9 are factors of 9. 7, 8, and have no common factors. So the least common multiple of 7, 8, and 9 are 7 X 8 X 9, which equals 504504
A factor is what a number is divisible by. 16: 1, 2, 4, 8, 16
Oh, dude, the largest two-digit number with exactly 7 factors is 48. Yeah, it's like a hidden gem in the world of numbers. It's got 1, 2, 3, 4, 6, 8, and 12 as factors, making it the cool kid with just the right amount of friends.
As 8 and 6 are both factors of the number, we want the lowest common multiple of 6 and 8 which is 24. There are at least 24 kids. (The number of kids is a multiple of 24.)
64 is the least number having exactly 7 factors: 1, 2, 4, 8, 16, 32, and 64.

8 (1,2,4,8)
24
88 has exactly eight factors (1, 2, 4, 8, 11, 22, 44 & 88)
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
8, 2*2*2
Any composite number. Examples: 4 and 9 . . . (three factors) 6, 8, and 10 . . . (four factors) 12 . . . (six factors) 60 . . . (twelve factors)
Indeed, the number 16 has 5 factors, 1, 2, 4, 8, and 16.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.
The least common multiple of 16 and 8 is 16. Because 16 is a multiple of 8, it is automatically the LCM of the pair. Another approach: To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 8 are 2 x 2 x 2. The prime factors of 16 are 2 x 2 x 2 x 2.
It is 30.
