Given numbers are 445,473,921,435

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

The LCM of 445,473,921,435 is 5621843865.

Find LCM of 445,473,921,435 with Prime Factorization

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

3 x 5 x 89 x 473 x 307 x 29 = 5621843865

Therefore, the lowest common multiple of 445,473,921,435 is 5621843865.

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.

445 x 473 x 921 x 435 = 84327657975

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.

445 : 1, 5, 89, 445

473 : 1, 11, 43, 473

921 : 1, 3, 307, 921

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,473,921,435, is 1.

Now, the common factors can be found like this.

445:5x 89

473:11x 43

921:3x 307

435:3x 5x 29

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 84327657975/(1x15)

LCM = 84327657975/15

LCM = 5621843865

Thus, we can understand that the LCM of 445,473,921,435 is 5621843865.
