Find LCM of 169,122,260,987,819 with Prime Factorization
| 2 | 169, 122, 260, 987, 819 |
| 3 | 169, 61, 130, 987, 819 |
| 7 | 169, 61, 130, 329, 273 |
| 13 | 169, 61, 130, 47, 39 |
| 13, 61, 10, 47, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 13 x 61 x 10 x 47 x 3 = 610498980
Therefore, the lowest common multiple of 169,122,260,987,819 is 610498980.
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.
169 x 122 x 260 x 987 x 819 = 4333321760040
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.
169 : 1, 13, 169
122 : 1, 2, 61, 122
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
987 : 1, 3, 7, 21, 47, 141, 329, 987
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,122,260,987,819, is 1.
Now, the common factors can be found like this.
169:13x 13
122:2x 61
260:2x 2x 5x 13
987:3x 7x 47
819:3x 3x 7x 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 7x 13x 13 = 7098
Therefore, the value for common factors is 7098.
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 = 4333321760040/(1x7098)
LCM = 4333321760040/7098
LCM = 610498980
Thus, we can understand that the LCM of 169,122,260,987,819 is 610498980.
