Given numbers are 879,747,400,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,747,400,816 is 1488322800.
Find LCM of 879,747,400,816 with Prime Factorization
| 2 | 879, 747, 400, 816 |
| 2 | 879, 747, 200, 408 |
| 2 | 879, 747, 100, 204 |
| 2 | 879, 747, 50, 102 |
| 3 | 879, 747, 25, 51 |
| 293, 249, 25, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 293 x 249 x 25 x 17 = 1488322800
Therefore, the lowest common multiple of 879,747,400,816 is 1488322800.
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.
879 x 747 x 400 x 816 = 214318483200
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.
879 : 1, 3, 293, 879
747 : 1, 3, 9, 83, 249, 747
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,747,400,816, is 1.
Now, the common factors can be found like this.
879:3x 293
747:3x 3x 83
400:2x 2x 2x 2x 5x 5
816:2x 2x 2x 2x 3x 17
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 = 214318483200/(1x144)
LCM = 214318483200/144
LCM = 1488322800
Thus, we can understand that the LCM of 879,747,400,816 is 1488322800.
