Given numbers are 668,692,944,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,692,944,960 is 1636386240.
Find LCM of 668,692,944,960 with Prime Factorization
| 2 | 668, 692, 944, 960 |
| 2 | 334, 346, 472, 480 |
| 2 | 167, 173, 236, 240 |
| 2 | 167, 173, 118, 120 |
| 167, 173, 59, 60 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 167 x 173 x 59 x 60 = 1636386240
Therefore, the lowest common multiple of 668,692,944,960 is 1636386240.
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 692 x 944 x 960 = 418914877440
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
692 : 1, 2, 4, 173, 346, 692
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,692,944,960, is 4.
Now, the common factors can be found like this.
668:2x 2x 167
692:2x 2x 173
944:2x 2x 2x 2x 59
960:2x 2x 2x 2x 2x 2x 3x 5
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 2 = 64
Therefore, the value for common factors is 64.
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 = 418914877440/(4x64)
LCM = 418914877440/256
LCM = 1636386240
Thus, we can understand that the LCM of 668,692,944,960 is 1636386240.
