Question

find the lcm .
please tell me step by step explanation in the image​

Answer 1

Write the factors of each

16m = 2 x 2 x 2 x 2 x m

-12m²n² = -1 x 3 x 4 x m x m x n x n

8n² = 2 x 4 x n x n

Take the highest power of common factors and multiply .

We get,

LCM = -1 x 2⁴ x m² x n² x 3 = - 48m²n²
