Given numbers are 278,864,638,718

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

The LCM of 278,864,638,718 is 13753514016.

Find LCM of 278,864,638,718 with Prime Factorization

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

2 x 139 x 432 x 319 x 359 = 13753514016

Therefore, the lowest common multiple of 278,864,638,718 is 13753514016.

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 864 x 638 x 718 = 110028112128

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

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

718 : 1, 2, 359, 718

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,864,638,718, is 2.

Now, the common factors can be found like this.

278:2x 139

864:2x 2x 2x 2x 2x 3x 3x 3

638:2x 11x 29

718:2x 359

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 = 110028112128/(2x4)

LCM = 110028112128/8

LCM = 13753514016

Thus, we can understand that the LCM of 278,864,638,718 is 13753514016.
