Answer:
396
Step-by-step explanation:
First, find the prime factorization of each number.
44 = 2^2 * 11
36 = 2^2 * 3^2
For the LCM, you need non-common factors and common factors with the larger exponent. Then you multiply together all the factors you use.
2 is a common factor. Both numbers have 2^2, so choose 2^2.
3 is not common. Use 3^2.
11 is not common. Use 11.
LCM = 2^2 * 3^2 * 11 = 396
Do #1- 32x4= 128, #2- 128x4= 512, do you also need to know the fractions? (I think)
