Given numbers are 221,702,104,442

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

The LCM of 221,702,104,442 is 47736.

Find LCM of 221,702,104,442 with Prime Factorization

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

2 x 13 x 17 x 1 x 27 x 4 x 1 = 47736

Therefore, the lowest common multiple of 221,702,104,442 is 47736.

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 702 x 104 x 442 = 7131567456

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

104 : 1, 2, 4, 8, 13, 26, 52, 104

442 : 1, 2, 13, 17, 26, 34, 221, 442

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,702,104,442, is 13.

Now, the common factors can be found like this.

221:13x 17

702:2x 3x 3x 3x 13

104:2x 2x 2x 13

442:2x 13x 17

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 13x 13x 17 = 11492

Therefore, the value for common factors is 11492.

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 = 7131567456/(13x11492)

LCM = 7131567456/149396

LCM = 47736

Thus, we can understand that the LCM of 221,702,104,442 is 47736.
