Find LCM of 168,896,689,375 with Prime Factorization
| 2 | 168, 896, 689, 375 |
| 2 | 84, 448, 689, 375 |
| 2 | 42, 224, 689, 375 |
| 3 | 21, 112, 689, 375 |
| 7 | 7, 112, 689, 125 |
| 1, 16, 689, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 1 x 16 x 689 x 125 = 231504000
Therefore, the lowest common multiple of 168,896,689,375 is 231504000.
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 896 x 689 x 375 = 38892672000
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
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
689 : 1, 13, 53, 689
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,896,689,375, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
896:2x 2x 2x 2x 2x 2x 2x 7
689:13x 53
375:3x 5x 5x 5
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 38892672000/(1x168)
LCM = 38892672000/168
LCM = 231504000
Thus, we can understand that the LCM of 168,896,689,375 is 231504000.
