Given numbers are 823,805,872,981

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

The LCM of 823,805,872,981 is 5199417720.

Find LCM of 823,805,872,981 with Prime Factorization

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

109 x 823 x 805 x 8 x 9 = 5199417720

Therefore, the lowest common multiple of 823,805,872,981 is 5199417720.

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.

823 x 805 x 872 x 981 = 566736531480

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.

823 : 1, 823

805 : 1, 5, 7, 23, 35, 115, 161, 805

872 : 1, 2, 4, 8, 109, 218, 436, 872

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,805,872,981, is 1.

Now, the common factors can be found like this.

823:823

805:5x 7x 23

872:2x 2x 2x 109

981:3x 3x 109

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

109 = 109

Therefore, the value for common factors is 109.

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 = 566736531480/(1x109)

LCM = 566736531480/109

LCM = 5199417720

Thus, we can understand that the LCM of 823,805,872,981 is 5199417720.
