Given numbers are 920,785,215,115

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

The LCM of 920,785,215,115 is 6210920.

Find LCM of 920,785,215,115 with Prime Factorization

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

5 x 23 x 8 x 157 x 43 x 1 = 6210920

Therefore, the lowest common multiple of 920,785,215,115 is 6210920.

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.

920 x 785 x 215 x 115 = 17856395000

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

785 : 1, 5, 157, 785

215 : 1, 5, 43, 215

115 : 1, 5, 23, 115

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,785,215,115, is 5.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

785:5x 157

215:5x 43

115:5x 23

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

5x 5x 23 = 575

Therefore, the value for common factors is 575.

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 = 17856395000/(5x575)

LCM = 17856395000/2875

LCM = 6210920

Thus, we can understand that the LCM of 920,785,215,115 is 6210920.
