Given numbers are 821,700,247,810

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

The LCM of 821,700,247,810 is 11498022900.

Find LCM of 821,700,247,810 with Prime Factorization

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

2 x 5 x 821 x 70 x 247 x 81 = 11498022900

Therefore, the lowest common multiple of 821,700,247,810 is 11498022900.

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 700 x 247 x 810 = 114980229000

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

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

247 : 1, 13, 19, 247

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 821,700,247,810, is 1.

Now, the common factors can be found like this.

821:821

700:2x 2x 5x 5x 7

247:13x 19

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 5 = 10

Therefore, the value for common factors is 10.

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 = 114980229000/(1x10)

LCM = 114980229000/10

LCM = 11498022900

Thus, we can understand that the LCM of 821,700,247,810 is 11498022900.
