Find LCM of 645,682,792,530,694 with Prime Factorization
| 2 | 645, 682, 792, 530, 694 |
| 3 | 645, 341, 396, 265, 347 |
| 5 | 215, 341, 132, 265, 347 |
| 11 | 43, 341, 132, 53, 347 |
| 43, 31, 12, 53, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 43 x 31 x 12 x 53 x 347 = 97080203880
Therefore, the lowest common multiple of 645,682,792,530,694 is 97080203880.
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.
645 x 682 x 792 x 530 x 694 = 128145869121600
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
682 : 1, 2, 11, 22, 31, 62, 341, 682
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
530 : 1, 2, 5, 10, 53, 106, 265, 530
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,682,792,530,694, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
682:2x 11x 31
792:2x 2x 2x 3x 3x 11
530:2x 5x 53
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 128145869121600/(1x1320)
LCM = 128145869121600/1320
LCM = 97080203880
Thus, we can understand that the LCM of 645,682,792,530,694 is 97080203880.
