Find LCM of 668,288,787,649,684 with Prime Factorization
| 2 | 668, 288, 787, 649, 684 |
| 2 | 334, 144, 787, 649, 342 |
| 3 | 167, 72, 787, 649, 171 |
| 3 | 167, 24, 787, 649, 57 |
| 167, 8, 787, 649, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 167 x 8 x 787 x 649 x 19 = 466747487712
Therefore, the lowest common multiple of 668,288,787,649,684 is 466747487712.
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.
668 x 288 x 787 x 649 x 684 = 67211638230528
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.
668 : 1, 2, 4, 167, 334, 668
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
787 : 1, 787
649 : 1, 11, 59, 649
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,288,787,649,684, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
288:2x 2x 2x 2x 2x 3x 3
787:787
649:11x 59
684:2x 2x 3x 3x 19
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 67211638230528/(1x144)
LCM = 67211638230528/144
LCM = 466747487712
Thus, we can understand that the LCM of 668,288,787,649,684 is 466747487712.
