The first multiple of any number is the number itself.
35
There are no first 5 multiple. Multiple is singular.
The first one is 5x1=5 the next is 5x2=10 The number itself is always the first multiple. This is important because when finding a common multiple, one needs to consider the number itself as a multiple Example: Find the least common multiple of 5 and 10, the answer is 10 since it is a multiple of itself and 5xs2 is 10.
Infinity but if you mean the lowest common multiple then it is 25
30
40
It is 65.
Least common multiple
The first common multiple of 4, 5, and 10 is their least common multiple (LCM), which is the smallest number that is a multiple of all three numbers. The LCM of 4, 5, and 10 is 20. The next common multiple would be the next multiple of 20, which is 40. The third common multiple would be the next multiple of 20, which is 60.
The first multiple of a number is the number itself.
Don't you mean least common multiple? The least common multiple is 210.
If you mean digit, the answer is NO.
