Given numbers are 225,634,386,516,638

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

The LCM of 225,634,386,516,638 is 755297799300.

Find LCM of 225,634,386,516,638 with Prime Factorization

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

2 x 3 x 75 x 317 x 193 x 86 x 319 = 755297799300

Therefore, the lowest common multiple of 225,634,386,516,638 is 755297799300.

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.

225 x 634 x 386 x 516 x 638 = 18127147183200

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.

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

634 : 1, 2, 317, 634

386 : 1, 2, 193, 386

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

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 225,634,386,516,638, is 1.

Now, the common factors can be found like this.

225:3x 3x 5x 5

634:2x 317

386:2x 193

516:2x 2x 3x 43

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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 18127147183200/(1x24)

LCM = 18127147183200/24

LCM = 755297799300

Thus, we can understand that the LCM of 225,634,386,516,638 is 755297799300.
