LCM Formula to Find Lowest Common Multiple of 720,128,128,256

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

720 x 128 x 128 x 256 = 3019898880

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

128 : 1, 2, 4, 8, 16, 32, 64, 128

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

16 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,128,128,256, is 16.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

128:2x 2x 2x 2x 2x 2x 2

256:2x 2x 2x 2x 2x 2x 2x 2

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2 = 16384

Therefore, the value for common factors is 16384.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 3019898880/(16x16384)

LCM = 3019898880/262144

LCM = 11520

Thus, we can understand that the LCM of 720,128,128,256 is 11520.
