LCM Formula to Find Lowest Common Multiple of 128,398,686,491

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 398 x 686 x 491 = 17159263744

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

398 : 1, 2, 199, 398

686 : 1, 2, 7, 14, 49, 98, 343, 686

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,398,686,491, is 1.

Now, the common factors can be found like this.

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

398:2x 199

686:2x 7x 7x 7

491:491

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17159263744/(1x4)

LCM = 17159263744/4

LCM = 4289815936

Thus, we can understand that the LCM of 128,398,686,491 is 4289815936.
