What is the lcm of 15 25 9 8.

Hi!

So, here we have to calculate the least common multiple of the numbers 15,25,9,8.

We have to break down every number as a prime number product:

15 = 3·525 = 5² 9 = 3² 8 = 2³

Then, we have to select common and uncommon numbers at the highest power so:

lcm : 2³·3²·5² = 8·9·25 = 1800
