Given numbers are 811,720,429,675

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

The LCM of 811,720,429,675 is 1252508400.

Find LCM of 811,720,429,675 with Prime Factorization

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

3 x 3 x 5 x 811 x 16 x 143 x 15 = 1252508400

Therefore, the lowest common multiple of 811,720,429,675 is 1252508400.

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.

811 x 720 x 429 x 675 = 169088634000

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.

811 : 1, 811

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

429 : 1, 3, 11, 13, 33, 39, 143, 429

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,720,429,675, is 1.

Now, the common factors can be found like this.

811:811

720:2x 2x 2x 2x 3x 3x 5

429:3x 11x 13

675:3x 3x 3x 5x 5

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

3x 3x 3x 5 = 135

Therefore, the value for common factors is 135.

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 = 169088634000/(1x135)

LCM = 169088634000/135

LCM = 1252508400

Thus, we can understand that the LCM of 811,720,429,675 is 1252508400.
