Given numbers are 474,816,143,925,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,816,143,925,915 is 520145511600.
Find LCM of 474,816,143,925,915 with Prime Factorization
| 2 | 474, 816, 143, 925, 915 |
| 3 | 237, 408, 143, 925, 915 |
| 5 | 79, 136, 143, 925, 305 |
| 79, 136, 143, 185, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 79 x 136 x 143 x 185 x 61 = 520145511600
Therefore, the lowest common multiple of 474,816,143,925,915 is 520145511600.
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.
474 x 816 x 143 x 925 x 915 = 46813096044000
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
143 : 1, 11, 13, 143
925 : 1, 5, 25, 37, 185, 925
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,816,143,925,915, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
816:2x 2x 2x 2x 3x 17
143:11x 13
925:5x 5x 37
915:3x 5x 61
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 5 = 90
Therefore, the value for common factors is 90.
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 = 46813096044000/(1x90)
LCM = 46813096044000/90
LCM = 520145511600
Thus, we can understand that the LCM of 474,816,143,925,915 is 520145511600.
