Given numbers are 668,480,622,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,480,622,249 is 2069170080.
Find LCM of 668,480,622,249 with Prime Factorization
| 2 | 668, 480, 622, 249 |
| 2 | 334, 240, 311, 249 |
| 3 | 167, 120, 311, 249 |
| 167, 40, 311, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 167 x 40 x 311 x 83 = 2069170080
Therefore, the lowest common multiple of 668,480,622,249 is 2069170080.
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 480 x 622 x 249 = 49660081920
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
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
622 : 1, 2, 311, 622
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,480,622,249, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
480:2x 2x 2x 2x 2x 3x 5
622:2x 311
249:3x 83
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 3 = 24
Therefore, the value for common factors is 24.
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 = 49660081920/(1x24)
LCM = 49660081920/24
LCM = 2069170080
Thus, we can understand that the LCM of 668,480,622,249 is 2069170080.
