Given numbers are 820,717,505,445

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

The LCM of 820,717,505,445 is 5284992660.

Find LCM of 820,717,505,445 with Prime Factorization

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

5 x 164 x 717 x 101 x 89 = 5284992660

Therefore, the lowest common multiple of 820,717,505,445 is 5284992660.

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.

820 x 717 x 505 x 445 = 132124816500

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.

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

717 : 1, 3, 239, 717

505 : 1, 5, 101, 505

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,717,505,445, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

717:3x 239

505:5x 101

445:5x 89

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 132124816500/(1x25)

LCM = 132124816500/25

LCM = 5284992660

Thus, we can understand that the LCM of 820,717,505,445 is 5284992660.
