Given numbers are 921,813,115,426

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

The LCM of 921,813,115,426 is 4075821030.

Find LCM of 921,813,115,426 with Prime Factorization

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

3 x 307 x 271 x 115 x 142 = 4075821030

Therefore, the lowest common multiple of 921,813,115,426 is 4075821030.

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 813 x 115 x 426 = 36682389270

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

813 : 1, 3, 271, 813

115 : 1, 5, 23, 115

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,813,115,426, is 1.

Now, the common factors can be found like this.

921:3x 307

813:3x 271

115:5x 23

426:2x 3x 71

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 = 36682389270/(1x9)

LCM = 36682389270/9

LCM = 4075821030

Thus, we can understand that the LCM of 921,813,115,426 is 4075821030.
