Given numbers are 138,643,412,365

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

The LCM of 138,643,412,365 is 6671909460.

Find LCM of 138,643,412,365 with Prime Factorization

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

2 x 69 x 643 x 206 x 365 = 6671909460

Therefore, the lowest common multiple of 138,643,412,365 is 6671909460.

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.

138 x 643 x 412 x 365 = 13343818920

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

643 : 1, 643

412 : 1, 2, 4, 103, 206, 412

365 : 1, 5, 73, 365

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,643,412,365, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

643:643

412:2x 2x 103

365:5x 73

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

2 = 2

Therefore, the value for common factors is 2.

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 = 13343818920/(1x2)

LCM = 13343818920/2

LCM = 6671909460

Thus, we can understand that the LCM of 138,643,412,365 is 6671909460.
