Question

Find the LCM of these numbers.
10 and 11?
Type the correct answer.

Answer 1

Multiplying the numbers will find the LCM unless they have a common factor greater than 1
In this case 11 is prime so LCM(10,11) = 10 x 11 = 110

LCM(12,25) = 12 x 25 = 300 because 12 and 25 are relatively prime (GCF = 1)
LCM(8,12) = 8 x 12 / 4 = 24 because the GCF(8,12) = 4

Answer 2

110

Explanation:

110 is the lowest number that is evenly divisible by 10 and 11. A good trick is to multiply the two numbers together for a common multiple, and in cases where the two numbers are so close in value like this is it usually the LCM.
