The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.
There are no multiples of ten.
60 and 120 are the two lowest common multiples.
10 is two in multiples of 2 to 100
They are 10 and 20
Because 10 is two fives so anything times ten is double as many fives.
60 and 120
There are two which are 1*10 = 10 and 2*10 = 20
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
109*1 = 109 and 109*10 = 1090 are two.
35 and 70 both have 7 and 5 as prime factors
