What is the least common multiple of 9 8 and 25?

Answer 1

With big LCM's like this, I use this method. Although not the most accurate it works:

9 x 8 x 25= 1800 this means all three numbers can go into 1800

1800/2 = 900 this is to try to find a smaller number into which all three numbers go into

Now check:

900/9=100

900/8=114

900/25 = 36 now that we know 900 is divisible by all three numbers we know it is a multiple of all three

Answer 2

1800
