#### Answer:

60

#### Explanation:

The multiples of 10 are 10,20,30,40,50,60,70 etc.

The multiples of 12 are 12,24,36, 48, 60

The smallest number which is a multiple of both 10 and 12 is 60

Or express both numbers in prime factor form:

10 =2x5

12=2x2x3

2 is common to both so the LCM is 2x2x3x5=60
