Given numbers are 164,845,326,402,642

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

The LCM of 164,845,326,402,642 is 485811729780.

Find LCM of 164,845,326,402,642 with Prime Factorization

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

2 x 3 x 82 x 845 x 163 x 67 x 107 = 485811729780

Therefore, the lowest common multiple of 164,845,326,402,642 is 485811729780.

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.

164 x 845 x 326 x 402 x 642 = 11659481514720

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.

164 : 1, 2, 4, 41, 82, 164

845 : 1, 5, 13, 65, 169, 845

326 : 1, 2, 163, 326

402 : 1, 2, 3, 6, 67, 134, 201, 402

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 164,845,326,402,642, is 1.

Now, the common factors can be found like this.

164:2x 2x 41

845:5x 13x 13

326:2x 163

402:2x 3x 67

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.

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 = 11659481514720/(1x24)

LCM = 11659481514720/24

LCM = 485811729780

Thus, we can understand that the LCM of 164,845,326,402,642 is 485811729780.
