Given numbers are 211,215,905,642

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

The LCM of 211,215,905,642 is 5271503730.

Find LCM of 211,215,905,642 with Prime Factorization

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

5 x 211 x 43 x 181 x 642 = 5271503730

Therefore, the lowest common multiple of 211,215,905,642 is 5271503730.

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.

211 x 215 x 905 x 642 = 26357518650

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.

211 : 1, 211

215 : 1, 5, 43, 215

905 : 1, 5, 181, 905

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,215,905,642, is 1.

Now, the common factors can be found like this.

211:211

215:5x 43

905:5x 181

642:2x 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.

5 = 5

Therefore, the value for common factors is 5.

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 = 26357518650/(1x5)

LCM = 26357518650/5

LCM = 5271503730

Thus, we can understand that the LCM of 211,215,905,642 is 5271503730.
