Given numbers are 158,638,838,860

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

The LCM of 158,638,838,860 is 9080928340.

Find LCM of 158,638,838,860 with Prime Factorization

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

2 x 79 x 319 x 419 x 430 = 9080928340

Therefore, the lowest common multiple of 158,638,838,860 is 9080928340.

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.

158 x 638 x 838 x 860 = 72647426720

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.

158 : 1, 2, 79, 158

638 : 1, 2, 11, 22, 29, 58, 319, 638

838 : 1, 2, 419, 838

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,638,838,860, is 2.

Now, the common factors can be found like this.

158:2x 79

638:2x 11x 29

838:2x 419

860:2x 2x 5x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 72647426720/(2x4)

LCM = 72647426720/8

LCM = 9080928340

Thus, we can understand that the LCM of 158,638,838,860 is 9080928340.
