Given numbers are 227,309,816,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 227,309,816,861 is 5475643152.
Find LCM of 227,309,816,861 with Prime Factorization
| 3 | 227, 309, 816, 861 |
| 227, 103, 272, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 227 x 103 x 272 x 287 = 5475643152
Therefore, the lowest common multiple of 227,309,816,861 is 5475643152.
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.
227 x 309 x 816 x 861 = 49280788368
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.
227 : 1, 227
309 : 1, 3, 103, 309
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,309,816,861, is 1.
Now, the common factors can be found like this.
227:227
309:3x 103
816:2x 2x 2x 2x 3x 17
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 49280788368/(1x9)
LCM = 49280788368/9
LCM = 5475643152
Thus, we can understand that the LCM of 227,309,816,861 is 5475643152.
