Given numbers are 638,718,460,368,254

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

The LCM of 638,718,460,368,254 is 26761267280.

Find LCM of 638,718,460,368,254 with Prime Factorization

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

2 x 2 x 23 x 319 x 359 x 5 x 4 x 127 = 26761267280

Therefore, the lowest common multiple of 638,718,460,368,254 is 26761267280.

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.

638 x 718 x 460 x 368 x 254 = 19696292718080

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.

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

718 : 1, 2, 359, 718

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

254 : 1, 2, 127, 254

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,718,460,368,254, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

718:2x 359

460:2x 2x 5x 23

368:2x 2x 2x 2x 23

254:2x 127

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

2x 2x 2x 2x 23 = 368

Therefore, the value for common factors is 368.

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 = 19696292718080/(2x368)

LCM = 19696292718080/736

LCM = 26761267280

Thus, we can understand that the LCM of 638,718,460,368,254 is 26761267280.
