Given numbers are 215,883,455,665

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

The LCM of 215,883,455,665 is 328242005.

Find LCM of 215,883,455,665 with Prime Factorization

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

5 x 7 x 43 x 883 x 13 x 19 = 328242005

Therefore, the lowest common multiple of 215,883,455,665 is 328242005.

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 883 x 455 x 665 = 57442350875

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

883 : 1, 883

455 : 1, 5, 7, 13, 35, 65, 91, 455

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,883,455,665, is 1.

Now, the common factors can be found like this.

215:5x 43

883:883

455:5x 7x 13

665:5x 7x 19

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 57442350875/(1x175)

LCM = 57442350875/175

LCM = 328242005

Thus, we can understand that the LCM of 215,883,455,665 is 328242005.
