Given numbers are 893,642,398,813

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

The LCM of 893,642,398,813 is 30917819274.

Find LCM of 893,642,398,813 with Prime Factorization

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

2 x 3 x 893 x 107 x 199 x 271 = 30917819274

Therefore, the lowest common multiple of 893,642,398,813 is 30917819274.

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.

893 x 642 x 398 x 813 = 185506915644

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.

893 : 1, 19, 47, 893

642 : 1, 2, 3, 6, 107, 214, 321, 642

398 : 1, 2, 199, 398

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,642,398,813, is 1.

Now, the common factors can be found like this.

893:19x 47

642:2x 3x 107

398:2x 199

813:3x 271

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 185506915644/(1x6)

LCM = 185506915644/6

LCM = 30917819274

Thus, we can understand that the LCM of 893,642,398,813 is 30917819274.
