Given numbers are 387,194,993,489

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

The LCM of 387,194,993,489 is 4050683334.

Find LCM of 387,194,993,489 with Prime Factorization

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

3 x 129 x 194 x 331 x 163 = 4050683334

Therefore, the lowest common multiple of 387,194,993,489 is 4050683334.

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.

387 x 194 x 993 x 489 = 36456150006

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.

387 : 1, 3, 9, 43, 129, 387

194 : 1, 2, 97, 194

993 : 1, 3, 331, 993

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,194,993,489, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

194:2x 97

993:3x 331

489:3x 163

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 36456150006/(1x9)

LCM = 36456150006/9

LCM = 4050683334

Thus, we can understand that the LCM of 387,194,993,489 is 4050683334.
