Calculate the LCM of 823,804,820,957

Given numbers are 823,804,820,957

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

The LCM of 823,804,820,957 is 43271348340.

Find LCM of 823,804,820,957 with Prime Factorization


2 823, 804, 820, 957
2 823, 402, 410, 957
3 823, 201, 205, 957
823, 67, 205, 319

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

2 x 2 x 3 x 823 x 67 x 205 x 319 = 43271348340

Therefore, the lowest common multiple of 823,804,820,957 is 43271348340.

LCM Formula to Find Lowest Common Multiple of 823,804,820,957

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 804 x 820 x 957 = 519256180080

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

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,804,820,957, is 1.

Now, the common factors can be found like this.

823:823

804:2x 2x 3x 67

820:2x 2x 5x 41

957:3x 11x 29

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 3 = 12

Therefore, the value for common factors is 12.

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 = 519256180080/(1x12)

LCM = 519256180080/12

LCM = 43271348340

Thus, we can understand that the LCM of 823,804,820,957 is 43271348340.
