Given numbers are 783,839,646,738,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,839,646,738,558 is 539388634842.
Find LCM of 783,839,646,738,558 with Prime Factorization
| 2 | 783, 839, 646, 738, 558 |
| 3 | 783, 839, 323, 369, 279 |
| 3 | 261, 839, 323, 123, 93 |
| 87, 839, 323, 41, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 87 x 839 x 323 x 41 x 31 = 539388634842
Therefore, the lowest common multiple of 783,839,646,738,558 is 539388634842.
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.
783 x 839 x 646 x 738 x 558 = 174761917688808
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
839 : 1, 839
646 : 1, 2, 17, 19, 34, 38, 323, 646
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,839,646,738,558, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
839:839
646:2x 17x 19
738:2x 3x 3x 41
558:2x 3x 3x 31
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 174761917688808/(1x324)
LCM = 174761917688808/324
LCM = 539388634842
Thus, we can understand that the LCM of 783,839,646,738,558 is 539388634842.
