Given numbers are 816,506,813,438

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

The LCM of 816,506,813,438 is 4084160784.

Find LCM of 816,506,813,438 with Prime Factorization

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

2 x 3 x 136 x 253 x 271 x 73 = 4084160784

Therefore, the lowest common multiple of 816,506,813,438 is 4084160784.

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.

816 x 506 x 813 x 438 = 147029788224

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

506 : 1, 2, 11, 22, 23, 46, 253, 506

813 : 1, 3, 271, 813

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,506,813,438, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

506:2x 11x 23

813:3x 271

438:2x 3x 73

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 147029788224/(1x36)

LCM = 147029788224/36

LCM = 4084160784

Thus, we can understand that the LCM of 816,506,813,438 is 4084160784.
