Given numbers are 861,273,966,882
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,273,966,882 is 10812438.
Find LCM of 861,273,966,882 with Prime Factorization
| 2 | 861, 273, 966, 882 |
| 3 | 861, 273, 483, 441 |
| 7 | 287, 91, 161, 147 |
| 41, 13, 23, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 13 x 23 x 21 = 10812438
Therefore, the lowest common multiple of 861,273,966,882 is 10812438.
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.
861 x 273 x 966 x 882 = 200267976636
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
273 : 1, 3, 7, 13, 21, 39, 91, 273
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
21 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,273,966,882, is 21.
Now, the common factors can be found like this.
861:3x 7x 41
273:3x 7x 13
966:2x 3x 7x 23
882:2x 3x 3x 7x 7
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 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 200267976636/(21x882)
LCM = 200267976636/18522
LCM = 10812438
Thus, we can understand that the LCM of 861,273,966,882 is 10812438.
