Because 20 is a multiple of 4. All multiples of 20 are also multipples of 2, 5 and 10
4, 8, 12, 16, 20
20 pinkgal333:20, 40, 60 are all common multiples.
All multiples of 20 are.
21
All the multiples of 20 cannot be listed since they are infinite in number. They start 20, 40, 60, 80, 100, ...
Multiples of 4: 4, 8, 12, 16, 20 Multiples of 10: 10, 20 Therefore, the answer is 20. (:
All multiples of 4 are also multiples of 2. e.g. 15 x 4 = 60. (60 is a multiple of 2 and 4) All multiples of 4 are even numbers. e.g. 4, 8, 12, 16, 18, 20, 24, 28 etc (these numbers all end in either 0,2,4,6, or 8.
Yes.
Since 10 is a factor of 20, all multiples of 20 are multiples of 10. This is also true of 1, 2, 4 and 5.
The first 5 multiples of 4 and 20 are 20, 40, 60, 80, 100
All multiples MUST be multiples of 4.
