Given numbers are 433,641,815,436,690

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

The LCM of 433,641,815,436,690 is 6805172128380.

Find LCM of 433,641,815,436,690 with Prime Factorization

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

2 x 5 x 433 x 641 x 163 x 218 x 69 = 6805172128380

Therefore, the lowest common multiple of 433,641,815,436,690 is 6805172128380.

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.

433 x 641 x 815 x 436 x 690 = 68051721283800

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.

433 : 1, 433

641 : 1, 641

815 : 1, 5, 163, 815

436 : 1, 2, 4, 109, 218, 436

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 433,641,815,436,690, is 1.

Now, the common factors can be found like this.

433:433

641:641

815:5x 163

436:2x 2x 109

690:2x 3x 5x 23

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 68051721283800/(1x10)

LCM = 68051721283800/10

LCM = 6805172128380

Thus, we can understand that the LCM of 433,641,815,436,690 is 6805172128380.
