Question

Find the least common multiple of 8y3 and 10y4

Answer 1

Answer:

$40y^4$

Step-by-step explanation:

To find the least common multiple (lcm) of a pair of numbers, we can multiple the numbers together and divide by the greatest common factor of those numbers. The greatest common factor (gcm) of $8y^3$ and $10y^4$ is $2y^3$, so

$lcm(8y^3, 10y^4)=\frac{8y^3\cdot10y^4}{2y^3} =4\cdot10y^4=40y^4$
