Find LCM of 648,418,739,286,824 with Prime Factorization
| 2 | 648, 418, 739, 286, 824 |
| 2 | 324, 209, 739, 143, 412 |
| 2 | 162, 209, 739, 143, 206 |
| 11 | 81, 209, 739, 143, 103 |
| 81, 19, 739, 13, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 81 x 19 x 739 x 13 x 103 = 134012808072
Therefore, the lowest common multiple of 648,418,739,286,824 is 134012808072.
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 418 x 739 x 286 x 824 = 47172508441344
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
739 : 1, 739
286 : 1, 2, 11, 13, 22, 26, 143, 286
824 : 1, 2, 4, 8, 103, 206, 412, 824
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,418,739,286,824, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
418:2x 11x 19
739:739
286:2x 11x 13
824:2x 2x 2x 103
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 11 = 352
Therefore, the value for common factors is 352.
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 = 47172508441344/(1x352)
LCM = 47172508441344/352
LCM = 134012808072
Thus, we can understand that the LCM of 648,418,739,286,824 is 134012808072.
