Given numbers are 813,456,626,810

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

The LCM of 813,456,626,810 is 5221703880.

Find LCM of 813,456,626,810 with Prime Factorization

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

2 x 3 x 271 x 76 x 313 x 135 = 5221703880

Therefore, the lowest common multiple of 813,456,626,810 is 5221703880.

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 456 x 626 x 810 = 187981339680

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

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

626 : 1, 2, 313, 626

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,456,626,810, is 1.

Now, the common factors can be found like this.

813:3x 271

456:2x 2x 2x 3x 19

626:2x 313

810:2x 3x 3x 3x 3x 5

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 = 187981339680/(1x36)

LCM = 187981339680/36

LCM = 5221703880

Thus, we can understand that the LCM of 813,456,626,810 is 5221703880.
