Find LCM of 287,715,990,949,683 with Prime Factorization
| 5 | 287, 715, 990, 949, 683 |
| 11 | 287, 143, 198, 949, 683 |
| 13 | 287, 13, 18, 949, 683 |
| 287, 1, 18, 73, 683 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 287 x 1 x 18 x 73 x 683 = 184163689710
Therefore, the lowest common multiple of 287,715,990,949,683 is 184163689710.
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.
287 x 715 x 990 x 949 x 683 = 131677038142650
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.
287 : 1, 7, 41, 287
715 : 1, 5, 11, 13, 55, 65, 143, 715
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
949 : 1, 13, 73, 949
683 : 1, 683
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,715,990,949,683, is 1.
Now, the common factors can be found like this.
287:7x 41
715:5x 11x 13
990:2x 3x 3x 5x 11
949:13x 73
683:683
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 13 = 715
Therefore, the value for common factors is 715.
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 = 131677038142650/(1x715)
LCM = 131677038142650/715
LCM = 184163689710
Thus, we can understand that the LCM of 287,715,990,949,683 is 184163689710.
