Calculate the LCM of 923,460,645,805

Given numbers are 923,460,645,805

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

The LCM of 923,460,645,805 is 383395740.

Find LCM of 923,460,645,805 with Prime Factorization


5 923, 460, 645, 805
23 923, 92, 129, 161
923, 4, 129, 7

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

5 x 23 x 923 x 4 x 129 x 7 = 383395740

Therefore, the lowest common multiple of 923,460,645,805 is 383395740.

LCM Formula to Find Lowest Common Multiple of 923,460,645,805

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.

923 x 460 x 645 x 805 = 220452550500

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.

923 : 1, 13, 71, 923

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

645 : 1, 3, 5, 15, 43, 129, 215, 645

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 923,460,645,805, is 1.

Now, the common factors can be found like this.

923:13x 71

460:2x 2x 5x 23

645:3x 5x 43

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.

5x 5x 23 = 575

Therefore, the value for common factors is 575.

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 = 220452550500/(1x575)

LCM = 220452550500/575

LCM = 383395740

Thus, we can understand that the LCM of 923,460,645,805 is 383395740.
