999 is a three-digit multiple of 9
-5
Using prime factorization, there are 2 three digit numbers with 9 factors: 512 and 768. There are no three digit numbers with 10 or more prime factors. 512=2^9 and 768=3*2^8
Here are two digit numbers that are divisible by both 6 and 9: 18 (which is the least common multiple) 36 54 72 90
It is 9
4, 8, 12, 16, 20, 24, 28, 32, and 36 are the first 9 multiples of 4.
The largest three-digit number is 999. To determine if it is a multiple of three, we can check if the sum of its digits (9 + 9 + 9 = 27) is divisible by three. Since 27 is divisible by three, 999 is the largest three-digit multiple of three.
No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.
9 isn't prime, but one three-digit multiple of 18 is 108.
108 is a multiple of 9 because 12 times 9 = 108
To be divisible by both 4 and 9 a number must be a multiple of the Least Common Factor of 4 and 9. The LCM is 36. The first 3 digit number in each hundred that is a multiple of 36 are as follows :- 108, 216, 324, 432, 504, 612, 720, 828 and 900.
The largest 3-digit number is 999. To check if it is a multiple of 3, you can sum the digits: 9 + 9 + 9 = 27, which is divisible by 3. Therefore, 999 is the largest 3-digit number that is a multiple of 3.
There isn't one.
90
54
A three-digit number is divisible by 9 if the sum of its digits is divisible by 9. For example, the number 108 is a three-digit number, and the sum of its digits (1 + 0 + 8) equals 9, which is divisible by 9. Other examples include 117 and 126.
The largest two-digit number that is a multiple of 9 is 90. However, since it must also be even, the largest even two-digit multiple of 9 is 72. Therefore, the largest two-digit number that meets both criteria is 72.
The least three-digit number that is divisible by both 5 and 9 is 135.
