Given numbers are 861,581,469,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,581,469,612 is 976756284.
Find LCM of 861,581,469,612 with Prime Factorization
| 3 | 861, 581, 469, 612 |
| 7 | 287, 581, 469, 204 |
| 41, 83, 67, 204 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 41 x 83 x 67 x 204 = 976756284
Therefore, the lowest common multiple of 861,581,469,612 is 976756284.
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 581 x 469 x 612 = 143583173748
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
581 : 1, 7, 83, 581
469 : 1, 7, 67, 469
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,581,469,612, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
581:7x 83
469:7x 67
612:2x 2x 3x 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.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 143583173748/(1x147)
LCM = 143583173748/147
LCM = 976756284
Thus, we can understand that the LCM of 861,581,469,612 is 976756284.
