Given numbers are 636,439,578,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,439,578,878 is 80689956.
Find LCM of 636,439,578,878 with Prime Factorization
| 2 | 636, 439, 578, 878 |
| 439 | 318, 439, 289, 439 |
| 318, 1, 289, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 439 x 318 x 1 x 289 x 1 = 80689956
Therefore, the lowest common multiple of 636,439,578,878 is 80689956.
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.
636 x 439 x 578 x 878 = 141691562736
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
439 : 1, 439
578 : 1, 2, 17, 34, 289, 578
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,439,578,878, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
439:439
578:2x 17x 17
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 439 = 1756
Therefore, the value for common factors is 1756.
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 = 141691562736/(1x1756)
LCM = 141691562736/1756
LCM = 80689956
Thus, we can understand that the LCM of 636,439,578,878 is 80689956.
