Given numbers are 813,618,189,39

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

The LCM of 813,618,189,39 is 137164482.

Find LCM of 813,618,189,39 with Prime Factorization

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

3 x 271 x 206 x 63 x 13 = 137164482

Therefore, the lowest common multiple of 813,618,189,39 is 137164482.

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.

813 x 618 x 189 x 39 = 3703441014

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.

813 : 1, 3, 271, 813

618 : 1, 2, 3, 6, 103, 206, 309, 618

189 : 1, 3, 7, 9, 21, 27, 63, 189

39 : 1, 3, 13, 39

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,618,189,39, is 3.

Now, the common factors can be found like this.

813:3x 271

618:2x 3x 103

189:3x 3x 3x 7

39:3x 13

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 = 3703441014/(3x9)

LCM = 3703441014/27

LCM = 137164482

Thus, we can understand that the LCM of 813,618,189,39 is 137164482.
