Given numbers are 381,919,247,919

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

The LCM of 381,919,247,919 is 86484333.

Find LCM of 381,919,247,919 with Prime Factorization

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

919 x 381 x 1 x 247 x 1 = 86484333

Therefore, the lowest common multiple of 381,919,247,919 is 86484333.

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.

381 x 919 x 247 x 919 = 79479102027

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.

381 : 1, 3, 127, 381

919 : 1, 919

247 : 1, 13, 19, 247

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,919,247,919, is 1.

Now, the common factors can be found like this.

381:3x 127

919:919

247:13x 19

919:919

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

919 = 919

Therefore, the value for common factors is 919.

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 = 79479102027/(1x919)

LCM = 79479102027/919

LCM = 86484333

Thus, we can understand that the LCM of 381,919,247,919 is 86484333.
