Find LCM of 560,961,645,265,920 with Prime Factorization
| 2 | 560, 961, 645, 265, 920 |
| 2 | 280, 961, 645, 265, 460 |
| 2 | 140, 961, 645, 265, 230 |
| 5 | 70, 961, 645, 265, 115 |
| 14, 961, 129, 53, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 14 x 961 x 129 x 53 x 23 = 84626198160
Therefore, the lowest common multiple of 560,961,645,265,920 is 84626198160.
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.
560 x 961 x 645 x 265 x 920 = 84626198160000
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
961 : 1, 31, 961
645 : 1, 3, 5, 15, 43, 129, 215, 645
265 : 1, 5, 53, 265
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,961,645,265,920, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
961:31x 31
645:3x 5x 43
265:5x 53
920:2x 2x 2x 5x 23
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 5x 5x 5 = 1000
Therefore, the value for common factors is 1000.
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 = 84626198160000/(1x1000)
LCM = 84626198160000/1000
LCM = 84626198160
Thus, we can understand that the LCM of 560,961,645,265,920 is 84626198160.
