Find LCM of 668,378,400,629,740 with Prime Factorization
| 2 | 668, 378, 400, 629, 740 |
| 2 | 334, 189, 200, 629, 370 |
| 5 | 167, 189, 100, 629, 185 |
| 37 | 167, 189, 20, 629, 37 |
| 167, 189, 20, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 167 x 189 x 20 x 17 x 1 = 7941250800
Therefore, the lowest common multiple of 668,378,400,629,740 is 7941250800.
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 378 x 400 x 629 x 740 = 47012204736000
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
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
629 : 1, 17, 37, 629
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,378,400,629,740, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
378:2x 3x 3x 3x 7
400:2x 2x 2x 2x 5x 5
629:17x 37
740:2x 2x 5x 37
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 5x 37 = 5920
Therefore, the value for common factors is 5920.
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 = 47012204736000/(1x5920)
LCM = 47012204736000/5920
LCM = 7941250800
Thus, we can understand that the LCM of 668,378,400,629,740 is 7941250800.
