The LCM of 12 and 28 is 84.
For small numbers, the easy way is to find the GCF and divide one of them by it, then multiply the result by the other number.
Factors of 12 are [2 2 3]
Factors of 28 are [2 2 7]
GCF=[2] = 4
Divide 28 by 4=7 and 7*12=84.
The proper way (which works for all numbers) is to take the highest power of all factors.
12 is 2^2 * 3^1
28 is 2^2 * 7^1
LCM is 2^2 * 3^1 * 7^1 (since 2^2 is the highest power of 2 in both numbers)
4 * 3 * 7 = 84
