The LCM of 684,297,661,738 is 611723772.
Find LCM of 684,297,661,738 with Prime Factorization
| 2 | 684, 297, 661, 738 |
| 3 | 342, 297, 661, 369 |
| 3 | 114, 99, 661, 123 |
| 38, 33, 661, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 38 x 33 x 661 x 41 = 611723772
Therefore, the lowest common multiple of 684,297,661,738 is 611723772.
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.
684 x 297 x 661 x 738 = 99099251064
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
297 : 1, 3, 9, 11, 27, 33, 99, 297
661 : 1, 661
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 684,297,661,738, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
297:3x 3x 3x 11
661:661
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 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 99099251064/(1x162)
LCM = 99099251064/162
LCM = 611723772
Thus, we can understand that the LCM of 684,297,661,738 is 611723772.
