Find LCM of 168,888,724,891,287 with Prime Factorization
| 2 | 168, 888, 724, 891, 287 |
| 2 | 84, 444, 362, 891, 287 |
| 2 | 42, 222, 181, 891, 287 |
| 3 | 21, 111, 181, 891, 287 |
| 7 | 7, 37, 181, 297, 287 |
| 1, 37, 181, 297, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 1 x 37 x 181 x 297 x 41 = 13700293992
Therefore, the lowest common multiple of 168,888,724,891,287 is 13700293992.
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.
168 x 888 x 724 x 891 x 287 = 27619792687872
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
724 : 1, 2, 4, 181, 362, 724
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,888,724,891,287, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
888:2x 2x 2x 3x 37
724:2x 2x 181
891:3x 3x 3x 3x 11
287:7x 41
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 2x 2x 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 27619792687872/(1x2016)
LCM = 27619792687872/2016
LCM = 13700293992
Thus, we can understand that the LCM of 168,888,724,891,287 is 13700293992.
