Given numbers are 278,574,586,685,731

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

The LCM of 278,574,586,685,731 is 11705831314030.

Find LCM of 278,574,586,685,731 with Prime Factorization

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

2 x 139 x 287 x 293 x 685 x 731 = 11705831314030

Therefore, the lowest common multiple of 278,574,586,685,731 is 11705831314030.

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.

278 x 574 x 586 x 685 x 731 = 46823325256120

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.

278 : 1, 2, 139, 278

574 : 1, 2, 7, 14, 41, 82, 287, 574

586 : 1, 2, 293, 586

685 : 1, 5, 137, 685

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,574,586,685,731, is 1.

Now, the common factors can be found like this.

278:2x 139

574:2x 7x 41

586:2x 293

685:5x 137

731:17x 43

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 = 46823325256120/(1x4)

LCM = 46823325256120/4

LCM = 11705831314030

Thus, we can understand that the LCM of 278,574,586,685,731 is 11705831314030.
