Given numbers are 217,921,885,229,372

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

The LCM of 217,921,885,229,372 is 54005358540.

Find LCM of 217,921,885,229,372 with Prime Factorization

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

3 x 31 x 7 x 307 x 295 x 229 x 4 = 54005358540

Therefore, the lowest common multiple of 217,921,885,229,372 is 54005358540.

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.

217 x 921 x 885 x 229 x 372 = 15067495032660

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.

217 : 1, 7, 31, 217

921 : 1, 3, 307, 921

885 : 1, 3, 5, 15, 59, 177, 295, 885

229 : 1, 229

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,921,885,229,372, is 1.

Now, the common factors can be found like this.

217:7x 31

921:3x 307

885:3x 5x 59

229:229

372:2x 2x 3x 31

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

3x 3x 31 = 279

Therefore, the value for common factors is 279.

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 = 15067495032660/(1x279)

LCM = 15067495032660/279

LCM = 54005358540

Thus, we can understand that the LCM of 217,921,885,229,372 is 54005358540.
