I think you mean some common multiples. Since 17 is prime, there are no common factors of 17 and 21. Now the first common multiple will be 21x17. You can use more 21s or more 17s to find additional multiples. Here is one 17x21x21 Here is another 17x17x21
The first five multiples of 21 are: 21, 42, 63, 84, 105.
The first 5 multiples of 21 are: 21, 42, 63, 84, and 105.
The first 5 multiples of 21 are: 21, 42, 63, 84, and 105.
The first 3 COMMON multiples of 17 will depend upon the OTHER NUMBER(S) with which 17 has common multiples. However, they will be regularly spaced within the multiples of 17.eg the first 3 COMMON multiples of:1 and 17 are 17, 34, 51;2 and 17 are: 34, 68, 102;5 and 17 are: 85, 170, 255;17 and 34 are: 34, 68, 102etc.
21, 42, 63, 84.
21, 42, 63, 84
The first 3 multiples of 7 are: 7, 14, and 21.
21, 42, 63, 84, 105.
They are: 21, 42 and 63
21, 42 and 63
