Find LCM of 912,754,739,551,645 with Prime Factorization
| 2 | 912, 754, 739, 551, 645 |
| 3 | 456, 377, 739, 551, 645 |
| 19 | 152, 377, 739, 551, 215 |
| 29 | 8, 377, 739, 29, 215 |
| 8, 13, 739, 1, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 29 x 8 x 13 x 739 x 1 x 215 = 54628476240
Therefore, the lowest common multiple of 912,754,739,551,645 is 54628476240.
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.
912 x 754 x 739 x 551 x 645 = 180601742449440
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
754 : 1, 2, 13, 26, 29, 58, 377, 754
739 : 1, 739
551 : 1, 19, 29, 551
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,754,739,551,645, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
754:2x 13x 29
739:739
551:19x 29
645:3x 5x 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 3x 19x 29 = 3306
Therefore, the value for common factors is 3306.
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 = 180601742449440/(1x3306)
LCM = 180601742449440/3306
LCM = 54628476240
Thus, we can understand that the LCM of 912,754,739,551,645 is 54628476240.
