Given numbers are 391,327,872,557

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

The LCM of 391,327,872,557 is 569730792.

Find LCM of 391,327,872,557 with Prime Factorization

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

109 x 391 x 3 x 8 x 557 = 569730792

Therefore, the lowest common multiple of 391,327,872,557 is 569730792.

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.

391 x 327 x 872 x 557 = 62100656328

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.

391 : 1, 17, 23, 391

327 : 1, 3, 109, 327

872 : 1, 2, 4, 8, 109, 218, 436, 872

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,327,872,557, is 1.

Now, the common factors can be found like this.

391:17x 23

327:3x 109

872:2x 2x 2x 109

557:557

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

109 = 109

Therefore, the value for common factors is 109.

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 = 62100656328/(1x109)

LCM = 62100656328/109

LCM = 569730792

Thus, we can understand that the LCM of 391,327,872,557 is 569730792.
