Given numbers are 416,198,790,215

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

The LCM of 416,198,790,215 is 699510240.

Find LCM of 416,198,790,215 with Prime Factorization

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

2 x 5 x 208 x 99 x 79 x 43 = 699510240

Therefore, the lowest common multiple of 416,198,790,215 is 699510240.

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.

416 x 198 x 790 x 215 = 13990204800

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.

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

790 : 1, 2, 5, 10, 79, 158, 395, 790

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,198,790,215, is 1.

Now, the common factors can be found like this.

416:2x 2x 2x 2x 2x 13

198:2x 3x 3x 11

790:2x 5x 79

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.

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 13990204800/(1x20)

LCM = 13990204800/20

LCM = 699510240

Thus, we can understand that the LCM of 416,198,790,215 is 699510240.
