Given numbers are 185,417,642,687

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

The LCM of 185,417,642,687 is 3780567870.

Find LCM of 185,417,642,687 with Prime Factorization

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

3 x 185 x 139 x 214 x 229 = 3780567870

Therefore, the lowest common multiple of 185,417,642,687 is 3780567870.

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.

185 x 417 x 642 x 687 = 34025110830

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.

185 : 1, 5, 37, 185

417 : 1, 3, 139, 417

642 : 1, 2, 3, 6, 107, 214, 321, 642

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,417,642,687, is 1.

Now, the common factors can be found like this.

185:5x 37

417:3x 139

642:2x 3x 107

687:3x 229

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 34025110830/(1x9)

LCM = 34025110830/9

LCM = 3780567870

Thus, we can understand that the LCM of 185,417,642,687 is 3780567870.
