Given numbers are 818,355,305,215

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

The LCM of 818,355,305,215 is 761692970.

Find LCM of 818,355,305,215 with Prime Factorization

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

5 x 818 x 71 x 61 x 43 = 761692970

Therefore, the lowest common multiple of 818,355,305,215 is 761692970.

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.

818 x 355 x 305 x 215 = 19042324250

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.

818 : 1, 2, 409, 818

355 : 1, 5, 71, 355

305 : 1, 5, 61, 305

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,355,305,215, is 1.

Now, the common factors can be found like this.

818:2x 409

355:5x 71

305:5x 61

215:5x 43

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 19042324250/(1x25)

LCM = 19042324250/25

LCM = 761692970

Thus, we can understand that the LCM of 818,355,305,215 is 761692970.
