Given numbers are 779,942,489,874,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,942,489,874,768 is 352138711296.
Find LCM of 779,942,489,874,768 with Prime Factorization
| 2 | 779, 942, 489, 874, 768 |
| 3 | 779, 471, 489, 437, 384 |
| 19 | 779, 157, 163, 437, 128 |
| 41, 157, 163, 23, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 41 x 157 x 163 x 23 x 128 = 352138711296
Therefore, the lowest common multiple of 779,942,489,874,768 is 352138711296.
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.
779 x 942 x 489 x 874 x 768 = 240862878526464
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.
779 : 1, 19, 41, 779
942 : 1, 2, 3, 6, 157, 314, 471, 942
489 : 1, 3, 163, 489
874 : 1, 2, 19, 23, 38, 46, 437, 874
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,942,489,874,768, is 1.
Now, the common factors can be found like this.
779:19x 41
942:2x 3x 157
489:3x 163
874:2x 19x 23
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 240862878526464/(1x684)
LCM = 240862878526464/684
LCM = 352138711296
Thus, we can understand that the LCM of 779,942,489,874,768 is 352138711296.
