Given numbers are 860,842,491,381

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

The LCM of 860,842,491,381 is 67730926260.

Find LCM of 860,842,491,381 with Prime Factorization

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

2 x 430 x 421 x 491 x 381 = 67730926260

Therefore, the lowest common multiple of 860,842,491,381 is 67730926260.

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.

860 x 842 x 491 x 381 = 135461852520

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

842 : 1, 2, 421, 842

491 : 1, 491

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,842,491,381, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

842:2x 421

491:491

381:3x 127

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 = 135461852520/(1x2)

LCM = 135461852520/2

LCM = 67730926260

Thus, we can understand that the LCM of 860,842,491,381 is 67730926260.
