Find LCM of 324,902,790,648 with Prime Factorization
| 2 | 324, 902, 790, 648 |
| 2 | 162, 451, 395, 324 |
| 3 | 81, 451, 395, 162 |
| 3 | 27, 451, 395, 54 |
| 3 | 9, 451, 395, 18 |
| 3 | 3, 451, 395, 6 |
| 1, 451, 395, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 1 x 451 x 395 x 2 = 115437960
Therefore, the lowest common multiple of 324,902,790,648 is 115437960.
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.
324 x 902 x 790 x 648 = 149607596160
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
902 : 1, 2, 11, 22, 41, 82, 451, 902
790 : 1, 2, 5, 10, 79, 158, 395, 790
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,902,790,648, is 2.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
902:2x 11x 41
790:2x 5x 79
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 149607596160/(2x648)
LCM = 149607596160/1296
LCM = 115437960
Thus, we can understand that the LCM of 324,902,790,648 is 115437960.
