Find LCM of 722,398,819,207,715 with Prime Factorization
| 2 | 722, 398, 819, 207, 715 |
| 3 | 361, 199, 819, 207, 715 |
| 3 | 361, 199, 273, 69, 715 |
| 13 | 361, 199, 91, 23, 715 |
| 361, 199, 7, 23, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 361 x 199 x 7 x 23 x 55 = 148855436730
Therefore, the lowest common multiple of 722,398,819,207,715 is 148855436730.
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.
722 x 398 x 819 x 207 x 715 = 34832172194820
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.
722 : 1, 2, 19, 38, 361, 722
398 : 1, 2, 199, 398
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
207 : 1, 3, 9, 23, 69, 207
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,398,819,207,715, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
398:2x 199
819:3x 3x 7x 13
207:3x 3x 23
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 34832172194820/(1x234)
LCM = 34832172194820/234
LCM = 148855436730
Thus, we can understand that the LCM of 722,398,819,207,715 is 148855436730.
