Find LCM of 649,286,664,663,738 with Prime Factorization
| 2 | 649, 286, 664, 663, 738 |
| 3 | 649, 143, 332, 663, 369 |
| 11 | 649, 143, 332, 221, 123 |
| 13 | 59, 13, 332, 221, 123 |
| 59, 1, 332, 17, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 59 x 1 x 332 x 17 x 123 = 35142399864
Therefore, the lowest common multiple of 649,286,664,663,738 is 35142399864.
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.
649 x 286 x 664 x 663 x 738 = 60304358166624
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.
649 : 1, 11, 59, 649
286 : 1, 2, 11, 13, 22, 26, 143, 286
664 : 1, 2, 4, 8, 83, 166, 332, 664
663 : 1, 3, 13, 17, 39, 51, 221, 663
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,286,664,663,738, is 1.
Now, the common factors can be found like this.
649:11x 59
286:2x 11x 13
664:2x 2x 2x 83
663:3x 13x 17
738:2x 3x 3x 41
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 11x 13 = 1716
Therefore, the value for common factors is 1716.
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 = 60304358166624/(1x1716)
LCM = 60304358166624/1716
LCM = 35142399864
Thus, we can understand that the LCM of 649,286,664,663,738 is 35142399864.
