Calculate the LCM of 323,989,781,805

Given numbers are 323,989,781,805

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

The LCM of 323,989,781,805 is 8732083745.

Find LCM of 323,989,781,805 with Prime Factorization


23 323, 989, 781, 805
323, 43, 781, 35

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

23 x 323 x 43 x 781 x 35 = 8732083745

Therefore, the lowest common multiple of 323,989,781,805 is 8732083745.

LCM Formula to Find Lowest Common Multiple of 323,989,781,805

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.

323 x 989 x 781 x 805 = 200837926135

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.

323 : 1, 17, 19, 323

989 : 1, 23, 43, 989

781 : 1, 11, 71, 781

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,989,781,805, is 1.

Now, the common factors can be found like this.

323:17x 19

989:23x 43

781:11x 71

805:5x 7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 200837926135/(1x23)

LCM = 200837926135/23

LCM = 8732083745

Thus, we can understand that the LCM of 323,989,781,805 is 8732083745.
