LCM Formula to Find Lowest Common Multiple of 128,730,120,768

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.

128 x 730 x 120 x 768 = 8611430400

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.

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

730 : 1, 2, 5, 10, 73, 146, 365, 730

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,730,120,768, is 2.

Now, the common factors can be found like this.

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

730:2x 5x 73

120:2x 2x 2x 3x 5

768:2x 2x 2x 2x 2x 2x 2x 2x 3

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 3x 5 = 15360

Therefore, the value for common factors is 15360.

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 = 8611430400/(2x15360)

LCM = 8611430400/30720

LCM = 280320

Thus, we can understand that the LCM of 128,730,120,768 is 280320.
