Given numbers are 923,643,520,497

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

The LCM of 923,643,520,497 is 166176920.

Find LCM of 923,643,520,497 with Prime Factorization

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

13 x 71 x 1 x 643 x 40 x 7 = 166176920

Therefore, the lowest common multiple of 923,643,520,497 is 166176920.

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 643 x 520 x 497 = 153381297160

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

643 : 1, 643

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,643,520,497, is 1.

Now, the common factors can be found like this.

923:13x 71

643:643

520:2x 2x 2x 5x 13

497:7x 71

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

13x 71 = 923

Therefore, the value for common factors is 923.

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 = 153381297160/(1x923)

LCM = 153381297160/923

LCM = 166176920

Thus, we can understand that the LCM of 923,643,520,497 is 166176920.
