It is: 30
The Greatest Common Multiple (GCM) of both 10 and 3 is 1.
The greatest number that is a multiple of both 2 and 5 is their least common multiple (LCM), which is 10. Since you are looking for the greatest number of 3, you can find the largest multiple of 10 that is less than or equal to 3, which is 0. Therefore, the greatest number of 3 that is divisible by both 2 and 5 is 0.
Any multiple of 12
Every multiple of 6 is.
Which number is a factor of 10 , but not a multiple of 5
15
12
Of course. There is 3. Remember, multiples of 3 can also be divided by 3, so the only prime number that is a multiple of 3 is 3.
No number that is a multiple of 3, can be a prime number. A prime number must only be divisible by itself and 1. It cannot be divisible by any other number. Therefore if it is a multiple of 3, then it must be divisible by 3 and hence, not a prime number.
Six.
A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.
As 9 is a multiple of 3, any multiple of 9 will do : 9,18,27,36,45,....
