Given numbers are 115,112,422,686

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

The LCM of 115,112,422,686 is 133166320.

Find LCM of 115,112,422,686 with Prime Factorization

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

2 x 7 x 115 x 8 x 211 x 49 = 133166320

Therefore, the lowest common multiple of 115,112,422,686 is 133166320.

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.

115 x 112 x 422 x 686 = 3728656960

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.

115 : 1, 5, 23, 115

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

422 : 1, 2, 211, 422

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,112,422,686, is 1.

Now, the common factors can be found like this.

115:5x 23

112:2x 2x 2x 2x 7

422:2x 211

686:2x 7x 7x 7

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 3728656960/(1x28)

LCM = 3728656960/28

LCM = 133166320

Thus, we can understand that the LCM of 115,112,422,686 is 133166320.
