it is 60 because 3 x 20=60 is like 3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3=60 but shorter and 10+10+10+10+10+10=60 and 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4=60 they all have it up to sixty so that's my answer? I could have put it the other way but i'm in a hurry so i put it this way because i know my three times tables my ten times table and my four times table

Least Common Multiple (LCM) for7 3 10is210
The LCM of 3 and 10 is 30.The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 3 and 10 is 1. So, the least common multiple is 3 x 10 ÷ 1 = 30.30
There is not a least common multiple of a single number, such as 10, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.Examples:The least common multiple of 8 and 10 is 40.The least common multiple of 10 and 35 is 70.The least common multiple of 10 and 43 is 430.The least common multiple of 3, 10, and 66 is 330.You need to provide two or more positive integer numbers to properly answer this.
The LCM of 3, 10, and 48 is 240
The LCM of 8, 9, and 10 is 360. 8 = 2^3 9 = 3^2 10 = 5 x 2 The least common multiple is therefore 2^3 x 3^2 x 5 = 360
