180 is divisible by 2, 3, 4, 5, 9, and 10.
420
32 ends in a 2 so is divisible at least by 2 [32/2 = 16] 95 ends in a 5 so is divisible at least by 5 [95/5 = 19]
30 is divisible by, and is the least common multiple of, 2, 3, and 5.

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.
The least three-digit number that is divisible by both 5 and 9 is 135.
To find a number less than 100 that is divisible by 2, 5, and 9, we need to find the least common multiple (LCM) of these three numbers. The LCM of 2, 5, and 9 is 90. Therefore, the number less than 100 that is divisible by 2, 5, and 9 is 90.
32 ends in a 2 so is divisible at least by 2 [32/2 = 16] 95 ends in a 5 so is divisible at least by 5 [95/5 = 19]
An "even" number is a number that is divisible by 2. Since 5 is not divisible by 2, it is an "odd" number.
A number that is divisible by 2, 3, 4, 5, and 10 must be divisible by the least common multiple of these numbers, which is 60. Therefore, any number that is a multiple of 60 will be divisible by 2, 3, 4, 5, and 10. This is because 60 is the smallest number that contains all the prime factors of 2, 3, 4, 5, and 10.
No all numbers ending in 0 (zero) are divisible by 10 and therfore divisible by at least 5 and 2. 1180 has the prime factors:2 * 2 * 5 * 59
