The least number that is divisible by 3, 5, and 9 is the least common multiple (LCM) of these numbers. To find the LCM, we first need to find the prime factorization of each number: 3 = 3, 5 = 5, and 9 = 3^2. The LCM is the product of the highest power of each prime factor that appears in the factorizations, so LCM(3, 5, 9) = 3^2 * 5 = 45. Therefore, the least number divisible by 3, 5, and 9 is 45.

No it is divisible by 5 at least 675/5 = 135 so also divisible by 135, and so on ...
No. 189 is only evenly divisible by 3 and 9 (from the set provided). Using the following rules of divisibility on the number 189: Divisible by 2? No - the number is not even Divisible by 3? Yes - the sum of the digits (1 + 8 + 9 = 18) is divisible by 3 Divisible by 4? No - the last two digits are not evenly divisible by 4 Divisible by 5? No - the last digit is not a 0 or a 5 Divisible by 6? No - the number is not even Divisible by 9? Yes - the sum of the digits is divisible by 9 Divisible by 10? No - the number is not divisible by 2 or 5
No. The sum of its digits, 5 + 3 + 1, is divisible by 3, which means the number itself is also divisible by 3.
Answer - How do you tell if a number is divisible by 3?you add all the digits in the number and see if that number can be divided by 3 Answer - A whole number is divisible by 3 if the sum of its digits is divisible by what?Three (3) Examples:* 27 -- 2+7=9 * 13452 -- 1+3+4+5+2=15 -- 1+5=6If the sum of the digits is divisible by 3, the number is also divisible by 3. Or just do the division.
30 is divisible by, and is the least common multiple of, 2, 3, and 5.

180 is divisible by 2, 3, 4, 5, 9, and 10.
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.

A number that is divisible by 15 is divisible both by 5 and 3 A number is divisible by 5 if it ends with 0 or 5 A number is divisible by 3 if the sum of its digits is divisible by 3 e.g. 4035 is divisible by 15 as it ends with a 5 and 4+0+3+5=12 which is divisible by 3
a number that is divisible by 3 and 5 but not by 4= 15
