Given numbers are 163,848,689,638

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

The LCM of 163,848,689,638 is 573214928.

Find LCM of 163,848,689,638 with Prime Factorization

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

2 x 53 x 163 x 8 x 13 x 319 = 573214928

Therefore, the lowest common multiple of 163,848,689,638 is 573214928.

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.

163 x 848 x 689 x 638 = 60760782368

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.

163 : 1, 163

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

689 : 1, 13, 53, 689

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 163,848,689,638, is 1.

Now, the common factors can be found like this.

163:163

848:2x 2x 2x 2x 53

689:13x 53

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 53 = 106

Therefore, the value for common factors is 106.

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 = 60760782368/(1x106)

LCM = 60760782368/106

LCM = 573214928

Thus, we can understand that the LCM of 163,848,689,638 is 573214928.
