To find the LCM of two numbers, you need to split them up into their prime factors first:
32=2x2x2x2x2
45=3x3x5
The next stage would be to identify any common factors, but as there are none we simply take all of these factors and multiply them together:
2x2x2x2x2x3x3x5=1,440
And so the LCM of 32 and 45 is 1,440

The Least Common Multiple (LCM) for 32 45 is 1,440. The GCF is 1.
lcm(5, 3) = 15 lcm(5, 45) = 45 lcm(3, 45) = 45 lcm(5, 3, 45) = 45
The answer to the LCM of 45 and 15 is 45.
The LCM is 32.
lcm(11, 27, 45) = 1485 11 = 11 27 = 33 45 = 32 x 5 lcm = 33 x 5 x 11 = 1485
