Given numbers are 861,276,943,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,276,943,746 is 29546076.
Find LCM of 861,276,943,746 with Prime Factorization
| 2 | 861, 276, 943, 746 |
| 3 | 861, 138, 943, 373 |
| 23 | 287, 46, 943, 373 |
| 41 | 287, 2, 41, 373 |
| 7, 2, 1, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 41 x 7 x 2 x 1 x 373 = 29546076
Therefore, the lowest common multiple of 861,276,943,746 is 29546076.
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 276 x 943 x 746 = 167171698008
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
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
943 : 1, 23, 41, 943
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,276,943,746, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
276:2x 2x 3x 23
943:23x 41
746:2x 373
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 23x 41 = 5658
Therefore, the value for common factors is 5658.
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 = 167171698008/(1x5658)
LCM = 167171698008/5658
LCM = 29546076
Thus, we can understand that the LCM of 861,276,943,746 is 29546076.
