To find the least common multiple (LCM) of a set of numbers, we need to determine the prime factors of each number. The numbers given are 2, 3, 4, 5, 6, 9, and 10. The prime factors of these numbers are 2, 3, 2^2, 5, 2 * 3, 3^2, and 2 * 5 respectively. To find the LCM, we need to take the highest power of each prime factor that appears in any of the numbers. Multiplying these highest powers together gives us the LCM, which in this case is 2^2 * 3^2 * 5 = 180. Therefore, the least number divisible by 2, 3, 4, 5, 6, 9, and 10 is 180.
6 because it is divisible by 2 and 3.

No it is not. A prime number is only divisible by 1 and itself, whereas 784 is at least divisible by the number 2 as well. 784/2=392
To find the least 4-digit number divisible by 2, 3, 4, 5, 6, and 7, we need to find the least common multiple (LCM) of these numbers. The LCM of 2, 3, 4, 5, 6, and 7 is 420. The smallest 4-digit number divisible by 420 is 1050. Therefore, 1050 is the least 4-digit number divisible by 2, 3, 4, 5, 6, and 7.
There is no number between 900 and 1000 that is divisible by 105 and 2.
