3 193, 9, 27, 13
3 193, 3, 9, 13
193, 1, 3, 13

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

2 x 3 x 3 x 3 x 3 x 3 x 193 x 1 x 3 x 13 = 3658122

Therefore, the lowest common multiple of 386,729,486,39 is 3658122.

LCM Formula to Find Lowest Common Multiple of 386,729,486,39

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 729 x 486 x 39 = 5333541876

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

729 : 1, 3, 9, 27, 81, 243, 729

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

39 : 1, 3, 13, 39

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,729,486,39, is 1.

Now, the common factors can be found like this.

386:2x 193

729:3x 3x 3x 3x 3x 3

486:2x 3x 3x 3x 3x 3

39:3x 13

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

2x 3x 3x 3x 3x 3x 3 = 1458

Therefore, the value for common factors is 1458.

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 = 5333541876/(1x1458)

LCM = 5333541876/1458

LCM = 3658122

Thus, we can understand that the LCM of 386,729,486,39 is 3658122.
