Given numbers are 687,437,806,194

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

The LCM of 687,437,806,194 is 23471721858.

Find LCM of 687,437,806,194 with Prime Factorization

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

2 x 687 x 437 x 403 x 97 = 23471721858

Therefore, the lowest common multiple of 687,437,806,194 is 23471721858.

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.

687 x 437 x 806 x 194 = 46943443716

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.

687 : 1, 3, 229, 687

437 : 1, 19, 23, 437

806 : 1, 2, 13, 26, 31, 62, 403, 806

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,437,806,194, is 1.

Now, the common factors can be found like this.

687:3x 229

437:19x 23

806:2x 13x 31

194:2x 97

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

2 = 2

Therefore, the value for common factors is 2.

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 = 46943443716/(1x2)

LCM = 46943443716/2

LCM = 23471721858

Thus, we can understand that the LCM of 687,437,806,194 is 23471721858.
