Given numbers are 821,819,418,133

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

The LCM of 821,819,418,133 is 281062782.

Find LCM of 821,819,418,133 with Prime Factorization

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

7 x 19 x 821 x 117 x 22 x 1 = 281062782

Therefore, the lowest common multiple of 821,819,418,133 is 281062782.

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.

821 x 819 x 418 x 133 = 37381350006

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.

821 : 1, 821

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

418 : 1, 2, 11, 19, 22, 38, 209, 418

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,819,418,133, is 1.

Now, the common factors can be found like this.

821:821

819:3x 3x 7x 13

418:2x 11x 19

133:7x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 37381350006/(1x133)

LCM = 37381350006/133

LCM = 281062782

Thus, we can understand that the LCM of 821,819,418,133 is 281062782.
