Given numbers are 287,266,787,228,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,266,787,228,843 is 14470975092.
Find LCM of 287,266,787,228,843 with Prime Factorization
| 2 | 287, 266, 787, 228, 843 |
| 3 | 287, 133, 787, 114, 843 |
| 7 | 287, 133, 787, 38, 281 |
| 19 | 41, 19, 787, 38, 281 |
| 41, 1, 787, 2, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 41 x 1 x 787 x 2 x 281 = 14470975092
Therefore, the lowest common multiple of 287,266,787,228,843 is 14470975092.
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.
287 x 266 x 787 x 228 x 843 = 11547838123416
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.
287 : 1, 7, 41, 287
266 : 1, 2, 7, 14, 19, 38, 133, 266
787 : 1, 787
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,266,787,228,843, is 1.
Now, the common factors can be found like this.
287:7x 41
266:2x 7x 19
787:787
228:2x 2x 3x 19
843:3x 281
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 7x 19 = 798
Therefore, the value for common factors is 798.
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 = 11547838123416/(1x798)
LCM = 11547838123416/798
LCM = 14470975092
Thus, we can understand that the LCM of 287,266,787,228,843 is 14470975092.
