Given numbers are 393,215,559,91

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

The LCM of 393,215,559,91 is 7689045.

Find LCM of 393,215,559,91 with Prime Factorization

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

13 x 43 x 393 x 5 x 1 x 7 = 7689045

Therefore, the lowest common multiple of 393,215,559,91 is 7689045.

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.

393 x 215 x 559 x 91 = 4298176155

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.

393 : 1, 3, 131, 393

215 : 1, 5, 43, 215

559 : 1, 13, 43, 559

91 : 1, 7, 13, 91

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,215,559,91, is 1.

Now, the common factors can be found like this.

393:3x 131

215:5x 43

559:13x 43

91:7x 13

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

13x 43 = 559

Therefore, the value for common factors is 559.

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 = 4298176155/(1x559)

LCM = 4298176155/559

LCM = 7689045

Thus, we can understand that the LCM of 393,215,559,91 is 7689045.
