Given numbers are 129,421,346,421,422

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

The LCM of 129,421,346,421,422 is 3964882854.

Find LCM of 129,421,346,421,422 with Prime Factorization

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

2 x 421 x 129 x 1 x 173 x 1 x 211 = 3964882854

Therefore, the lowest common multiple of 129,421,346,421,422 is 3964882854.

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.

129 x 421 x 346 x 421 x 422 = 3338431363068

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.

129 : 1, 3, 43, 129

421 : 1, 421

346 : 1, 2, 173, 346

421 : 1, 421

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,421,346,421,422, is 1.

Now, the common factors can be found like this.

129:3x 43

421:421

346:2x 173

421:421

422:2x 211

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

2x 421 = 842

Therefore, the value for common factors is 842.

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 = 3338431363068/(1x842)

LCM = 3338431363068/842

LCM = 3964882854

Thus, we can understand that the LCM of 129,421,346,421,422 is 3964882854.
