Given numbers are 215,518,328,86

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

The LCM of 215,518,328,86 is 18264680.

Find LCM of 215,518,328,86 with Prime Factorization

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

2 x 43 x 5 x 259 x 164 x 1 = 18264680

Therefore, the lowest common multiple of 215,518,328,86 is 18264680.

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.

215 x 518 x 328 x 86 = 3141524960

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.

215 : 1, 5, 43, 215

518 : 1, 2, 7, 14, 37, 74, 259, 518

328 : 1, 2, 4, 8, 41, 82, 164, 328

86 : 1, 2, 43, 86

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,518,328,86, is 1.

Now, the common factors can be found like this.

215:5x 43

518:2x 7x 37

328:2x 2x 2x 41

86:2x 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 2x 43 = 172

Therefore, the value for common factors is 172.

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 = 3141524960/(1x172)

LCM = 3141524960/172

LCM = 18264680

Thus, we can understand that the LCM of 215,518,328,86 is 18264680.
