Given numbers are 715,815,805,205

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

The LCM of 715,815,805,205 is 769313545.

Find LCM of 715,815,805,205 with Prime Factorization

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

5 x 143 x 163 x 161 x 41 = 769313545

Therefore, the lowest common multiple of 715,815,805,205 is 769313545.

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.

715 x 815 x 805 x 205 = 96164193125

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

815 : 1, 5, 163, 815

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

205 : 1, 5, 41, 205

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,815,805,205, is 5.

Now, the common factors can be found like this.

715:5x 11x 13

815:5x 163

805:5x 7x 23

205:5x 41

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 = 96164193125/(5x25)

LCM = 96164193125/125

LCM = 769313545

Thus, we can understand that the LCM of 715,815,805,205 is 769313545.
