Find LCM of 648,947,172,259,675 with Prime Factorization
| 2 | 648, 947, 172, 259, 675 |
| 2 | 324, 947, 86, 259, 675 |
| 3 | 162, 947, 43, 259, 675 |
| 3 | 54, 947, 43, 259, 225 |
| 3 | 18, 947, 43, 259, 75 |
| 6, 947, 43, 259, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 6 x 947 x 43 x 259 x 25 = 170857171800
Therefore, the lowest common multiple of 648,947,172,259,675 is 170857171800.
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.
648 x 947 x 172 x 259 x 675 = 18452574554400
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
947 : 1, 947
172 : 1, 2, 4, 43, 86, 172
259 : 1, 7, 37, 259
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,947,172,259,675, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
947:947
172:2x 2x 43
259:7x 37
675:3x 3x 3x 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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 18452574554400/(1x108)
LCM = 18452574554400/108
LCM = 170857171800
Thus, we can understand that the LCM of 648,947,172,259,675 is 170857171800.
