Find LCM of 507,645,689,265,338 with Prime Factorization
| 3 | 507, 645, 689, 265, 338 |
| 5 | 169, 215, 689, 265, 338 |
| 13 | 169, 43, 689, 53, 338 |
| 13 | 13, 43, 53, 53, 26 |
| 53 | 1, 43, 53, 53, 2 |
| 1, 43, 1, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 13 x 53 x 1 x 43 x 1 x 1 x 2 = 11554530
Therefore, the lowest common multiple of 507,645,689,265,338 is 11554530.
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.
507 x 645 x 689 x 265 x 338 = 20181315415950
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.
507 : 1, 3, 13, 39, 169, 507
645 : 1, 3, 5, 15, 43, 129, 215, 645
689 : 1, 13, 53, 689
265 : 1, 5, 53, 265
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,645,689,265,338, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
645:3x 5x 43
689:13x 53
265:5x 53
338:2x 13x 13
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 13x 13x 13x 53 = 1746615
Therefore, the value for common factors is 1746615.
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 = 20181315415950/(1x1746615)
LCM = 20181315415950/1746615
LCM = 11554530
Thus, we can understand that the LCM of 507,645,689,265,338 is 11554530.
