Given numbers are 816,439,585,779,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,439,585,779,977 is 53164448335440.
Find LCM of 816,439,585,779,977 with Prime Factorization
| 3 | 816, 439, 585, 779, 977 |
| 272, 439, 195, 779, 977 |
Multiply the prime numbers at the bottom and the left side.
3 x 272 x 439 x 195 x 779 x 977 = 53164448335440
Therefore, the lowest common multiple of 816,439,585,779,977 is 53164448335440.
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.
816 x 439 x 585 x 779 x 977 = 159493345006320
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
439 : 1, 439
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
779 : 1, 19, 41, 779
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,439,585,779,977, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
439:439
585:3x 3x 5x 13
779:19x 41
977:977
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 159493345006320/(1x3)
LCM = 159493345006320/3
LCM = 53164448335440
Thus, we can understand that the LCM of 816,439,585,779,977 is 53164448335440.
