Given numbers are 439,756,820,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 439,756,820,878 is 68036220.
Find LCM of 439,756,820,878 with Prime Factorization
| 2 | 439, 756, 820, 878 |
| 2 | 439, 378, 410, 439 |
| 439 | 439, 189, 205, 439 |
| 1, 189, 205, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 439 x 1 x 189 x 205 x 1 = 68036220
Therefore, the lowest common multiple of 439,756,820,878 is 68036220.
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.
439 x 756 x 820 x 878 = 238943204640
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.
439 : 1, 439
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,756,820,878, is 1.
Now, the common factors can be found like this.
439:439
756:2x 2x 3x 3x 3x 7
820:2x 2x 5x 41
878:2x 439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 439 = 3512
Therefore, the value for common factors is 3512.
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 = 238943204640/(1x3512)
LCM = 238943204640/3512
LCM = 68036220
Thus, we can understand that the LCM of 439,756,820,878 is 68036220.
