Given numbers are 109,290,842,654,221

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

The LCM of 109,290,842,654,221 is 8823078030.

Find LCM of 109,290,842,654,221 with Prime Factorization

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

2 x 109 x 1 x 145 x 421 x 3 x 221 = 8823078030

Therefore, the lowest common multiple of 109,290,842,654,221 is 8823078030.

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.

109 x 290 x 842 x 654 x 221 = 3846862021080

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.

109 : 1, 109

290 : 1, 2, 5, 10, 29, 58, 145, 290

842 : 1, 2, 421, 842

654 : 1, 2, 3, 6, 109, 218, 327, 654

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,290,842,654,221, is 1.

Now, the common factors can be found like this.

109:109

290:2x 5x 29

842:2x 421

654:2x 3x 109

221:13x 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 109 = 436

Therefore, the value for common factors is 436.

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 = 3846862021080/(1x436)

LCM = 3846862021080/436

LCM = 8823078030

Thus, we can understand that the LCM of 109,290,842,654,221 is 8823078030.
