Since you didn't specify a single number, and all numbers are multiples of themselves, the five smallest multiples are the counting numbers 1 to 5.
The LCM of two consecutive numbers is their product. The LCM of two consecutive multiples of 5 is their product divided by 5. Two consecutive numbers cannot be multiples of 5.
All numbers do.
5, 10, and 20 are all multiples of 5 and factors of 20.
5 of them.
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
Multiples of 5.
All multiples of 5 are numbers ending in either 5 or 0.
the common multiples of 5 and 6 is 30
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
To find numbers that are multiples of both 3 and 5, we need to find the numbers that are common multiples of both 3 and 5. These are numbers that are divisible by the least common multiple of 3 and 5, which is 15. The first four numbers less than 70 that are multiples of both 3 and 5 are 15, 30, 45, and 60.
Since you didn't specify a single number, and all numbers are multiples of themselves, the five smallest multiples are the counting numbers 1 to 5.
Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
All decimals, and all whole numbers that do not end in zero or 5, are not multiples of 5 .
60 and all multiples of 60.
All non-zero numbers have an infinite amount of multiples. There are no numbers with exactly five.
