Find LCM of 288,161,388,989,688 with Prime Factorization
| 2 | 288, 161, 388, 989, 688 |
| 2 | 144, 161, 194, 989, 344 |
| 2 | 72, 161, 97, 989, 172 |
| 2 | 36, 161, 97, 989, 86 |
| 23 | 18, 161, 97, 989, 43 |
| 43 | 18, 7, 97, 43, 43 |
| 18, 7, 97, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 43 x 18 x 7 x 97 x 1 x 1 = 193400928
Therefore, the lowest common multiple of 288,161,388,989,688 is 193400928.
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.
288 x 161 x 388 x 989 x 688 = 12241505138688
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
161 : 1, 7, 23, 161
388 : 1, 2, 4, 97, 194, 388
989 : 1, 23, 43, 989
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,161,388,989,688, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
161:7x 23
388:2x 2x 97
989:23x 43
688:2x 2x 2x 2x 43
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 2x 23x 43 = 63296
Therefore, the value for common factors is 63296.
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 = 12241505138688/(1x63296)
LCM = 12241505138688/63296
LCM = 193400928
Thus, we can understand that the LCM of 288,161,388,989,688 is 193400928.
