Given numbers are 905,213,342,321

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

The LCM of 905,213,342,321 is 2351347470.

Find LCM of 905,213,342,321 with Prime Factorization

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

3 x 905 x 71 x 114 x 107 = 2351347470

Therefore, the lowest common multiple of 905,213,342,321 is 2351347470.

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.

905 x 213 x 342 x 321 = 21162127230

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.

905 : 1, 5, 181, 905

213 : 1, 3, 71, 213

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,213,342,321, is 1.

Now, the common factors can be found like this.

905:5x 181

213:3x 71

342:2x 3x 3x 19

321:3x 107

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 21162127230/(1x9)

LCM = 21162127230/9

LCM = 2351347470

Thus, we can understand that the LCM of 905,213,342,321 is 2351347470.
