Given numbers are 491,578,570,638

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

The LCM of 491,578,570,638 is 25801495170.

Find LCM of 491,578,570,638 with Prime Factorization

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

2 x 491 x 289 x 285 x 319 = 25801495170

Therefore, the lowest common multiple of 491,578,570,638 is 25801495170.

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.

491 x 578 x 570 x 638 = 103205980680

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.

491 : 1, 491

578 : 1, 2, 17, 34, 289, 578

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,578,570,638, is 1.

Now, the common factors can be found like this.

491:491

578:2x 17x 17

570:2x 3x 5x 19

638:2x 11x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 103205980680/(1x4)

LCM = 103205980680/4

LCM = 25801495170

Thus, we can understand that the LCM of 491,578,570,638 is 25801495170.
