Given numbers are 921,805,794,406

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

The LCM of 921,805,794,406 is 17071591530.

Find LCM of 921,805,794,406 with Prime Factorization

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

2 x 7 x 921 x 115 x 397 x 29 = 17071591530

Therefore, the lowest common multiple of 921,805,794,406 is 17071591530.

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.

921 x 805 x 794 x 406 = 239002281420

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.

921 : 1, 3, 307, 921

805 : 1, 5, 7, 23, 35, 115, 161, 805

794 : 1, 2, 397, 794

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,805,794,406, is 1.

Now, the common factors can be found like this.

921:3x 307

805:5x 7x 23

794:2x 397

406:2x 7x 29

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 239002281420/(1x14)

LCM = 239002281420/14

LCM = 17071591530

Thus, we can understand that the LCM of 921,805,794,406 is 17071591530.
