Given numbers are 221,841,771,442

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

The LCM of 221,841,771,442 is 286597662.

Find LCM of 221,841,771,442 with Prime Factorization

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

13 x 17 x 1 x 841 x 771 x 2 = 286597662

Therefore, the lowest common multiple of 221,841,771,442 is 286597662.

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 841 x 771 x 442 = 63338083302

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

841 : 1, 29, 841

771 : 1, 3, 257, 771

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,841,771,442, is 1.

Now, the common factors can be found like this.

221:13x 17

841:29x 29

771:3x 257

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.

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 63338083302/(1x221)

LCM = 63338083302/221

LCM = 286597662

Thus, we can understand that the LCM of 221,841,771,442 is 286597662.
