Find LCM of 715,819,605,375 with Prime Factorization
| 3 | 715, 819, 605, 375 |
| 5 | 715, 273, 605, 125 |
| 11 | 143, 273, 121, 25 |
| 13 | 13, 273, 11, 25 |
| 1, 21, 11, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 1 x 21 x 11 x 25 = 12387375
Therefore, the lowest common multiple of 715,819,605,375 is 12387375.
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 819 x 605 x 375 = 132854596875
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
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
605 : 1, 5, 11, 55, 121, 605
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,819,605,375, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
819:3x 3x 7x 13
605:5x 11x 11
375:3x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11x 13 = 10725
Therefore, the value for common factors is 10725.
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 = 132854596875/(1x10725)
LCM = 132854596875/10725
LCM = 12387375
Thus, we can understand that the LCM of 715,819,605,375 is 12387375.
