The LCM of 869,382,136,663,981 is 287875305432.
Find LCM of 869,382,136,663,981 with Prime Factorization
| 2 | 869, 382, 136, 663, 981 |
| 3 | 869, 191, 68, 663, 981 |
| 17 | 869, 191, 68, 221, 327 |
| 869, 191, 4, 13, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 869 x 191 x 4 x 13 x 327 = 287875305432
Therefore, the lowest common multiple of 869,382,136,663,981 is 287875305432.
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.
869 x 382 x 136 x 663 x 981 = 29363281154064
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.
869 : 1, 11, 79, 869
382 : 1, 2, 191, 382
136 : 1, 2, 4, 8, 17, 34, 68, 136
663 : 1, 3, 13, 17, 39, 51, 221, 663
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,382,136,663,981, is 1.
Now, the common factors can be found like this.
869:11x 79
382:2x 191
136:2x 2x 2x 17
663:3x 13x 17
981:3x 3x 109
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 17 = 102
Therefore, the value for common factors is 102.
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 = 29363281154064/(1x102)
LCM = 29363281154064/102
LCM = 287875305432
Thus, we can understand that the LCM of 869,382,136,663,981 is 287875305432.
