Given numbers are 817,158,133,869

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

The LCM of 817,158,133,869 is 9939622.

Find LCM of 817,158,133,869 with Prime Factorization

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

19 x 79 x 43 x 2 x 7 x 11 = 9939622

Therefore, the lowest common multiple of 817,158,133,869 is 9939622.

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.

817 x 158 x 133 x 869 = 14919372622

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.

817 : 1, 19, 43, 817

158 : 1, 2, 79, 158

133 : 1, 7, 19, 133

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,158,133,869, is 1.

Now, the common factors can be found like this.

817:19x 43

158:2x 79

133:7x 19

869:11x 79

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

19x 79 = 1501

Therefore, the value for common factors is 1501.

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 = 14919372622/(1x1501)

LCM = 14919372622/1501

LCM = 9939622

Thus, we can understand that the LCM of 817,158,133,869 is 9939622.
