Given numbers are 209,113,347,404,642

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

The LCM of 209,113,347,404,642 is 1062773218716.

Find LCM of 209,113,347,404,642 with Prime Factorization

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

2 x 209 x 113 x 347 x 202 x 321 = 1062773218716

Therefore, the lowest common multiple of 209,113,347,404,642 is 1062773218716.

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.

209 x 113 x 347 x 404 x 642 = 2125546437432

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.

209 : 1, 11, 19, 209

113 : 1, 113

347 : 1, 347

404 : 1, 2, 4, 101, 202, 404

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,113,347,404,642, is 1.

Now, the common factors can be found like this.

209:11x 19

113:113

347:347

404:2x 2x 101

642:2x 3x 107

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 = 2125546437432/(1x2)

LCM = 2125546437432/2

LCM = 1062773218716

Thus, we can understand that the LCM of 209,113,347,404,642 is 1062773218716.
