Given numbers are 386,644,424

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 386,644,424 is 13174952.

Find LCM of 386,644,424 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 193 x 161 x 106 = 13174952

Therefore, the lowest common multiple of 386,644,424 is 13174952.

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.

386 x 644 x 424 = 105399616

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.

386 : 1, 2, 193, 386

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

424 : 1, 2, 4, 8, 53, 106, 212, 424

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,644,424, is 2.

Now, the common factors can be found like this.

386:2x 193

644:2x 2x 7x 23

424:2x 2x 2x 53

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 = 105399616/(2x4)

LCM = 105399616/8

LCM = 13174952

Thus, we can understand that the LCM of 386,644,424 is 13174952.

Here are some samples of LCM of two or more Numbers calculations.
