The six multiples are: 57 x 1 = 57 57 x 2 = 114 57 x 3 = 171 57 x 4 = 228 57 x 5 = 285 57 x 6 = 342
Because they are multiples of 5. All multiples of 5 have 5 as a factor, which means they are divisible by 5.
Multiples of 5 and 10 are called common multiples.
There are an infinite number of multiples of 5
multiples of 5 end in -0 or -5
The first 5 positive integer multiples of 57 are: 1 x 57 = 57 2 x 57 = 114 3 x 57 = 171 4 x 57 = 228 5 x 57 = 285
The six multiples are: 57 x 1 = 57 57 x 2 = 114 57 x 3 = 171 57 x 4 = 228 57 x 5 = 285 57 x 6 = 342
19, 38, 57, 76, 95
The multiples of 57 are 57*2, 57*3, 57*4, 57*5 and so on. The first ten are 114, 171, 228, 285, 342, 399, 456, 513, 570, and 627. The multiples of 123 are 123*2, 123*3, 123*4, 123*5, and so on. The first ten are 246, 369, 492, 615, 738, 861, 984, 1107, 1230, and 1353. Numbers that are multiples of both appear in both lists, for example 7011 and 14022. (The lists above are not long enough to show the numbers that appear in both lists; they would have to be extended).
-14
Any of its multiples including itself
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
Because they are multiples of 5. All multiples of 5 have 5 as a factor, which means they are divisible by 5.
3,6,9,12,15,18,21,24,27,30,33,36,39,42are multiples of 3 5,10,15,20,25,30,35,40,45,50,55,60,65,are multiples of 5
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
Multiples of 5 and 10 are called common multiples.
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also of 5.
