Given numbers are 823,307,821,823

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

The LCM of 823,307,821,823 is 207434681.

Find LCM of 823,307,821,823 with Prime Factorization

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

823 x 1 x 307 x 821 x 1 = 207434681

Therefore, the lowest common multiple of 823,307,821,823 is 207434681.

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 307 x 821 x 823 = 170718742463

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

307 : 1, 307

821 : 1, 821

823 : 1, 823

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,307,821,823, is 1.

Now, the common factors can be found like this.

823:823

307:307

821:821

823:823

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

823 = 823

Therefore, the value for common factors is 823.

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 = 170718742463/(1x823)

LCM = 170718742463/823

LCM = 207434681

Thus, we can understand that the LCM of 823,307,821,823 is 207434681.
