Given numbers are 221,215,884,194

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

The LCM of 221,215,884,194 is 18435820.

Find LCM of 221,215,884,194 with Prime Factorization

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

2 x 13 x 17 x 1 x 215 x 2 x 97 = 18435820

Therefore, the lowest common multiple of 221,215,884,194 is 18435820.

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.

221 x 215 x 884 x 194 = 8148632440

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.

221 : 1, 13, 17, 221

215 : 1, 5, 43, 215

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,215,884,194, is 1.

Now, the common factors can be found like this.

221:13x 17

215:5x 43

884:2x 2x 13x 17

194:2x 97

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

2x 13x 17 = 442

Therefore, the value for common factors is 442.

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 = 8148632440/(1x442)

LCM = 8148632440/442

LCM = 18435820

Thus, we can understand that the LCM of 221,215,884,194 is 18435820.
