Given numbers are 843,646,391,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,646,391,779 is 513537054.
Find LCM of 843,646,391,779 with Prime Factorization
| 17 | 843, 646, 391, 779 |
| 19 | 843, 38, 23, 779 |
| 843, 2, 23, 41 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 843 x 2 x 23 x 41 = 513537054
Therefore, the lowest common multiple of 843,646,391,779 is 513537054.
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.
843 x 646 x 391 x 779 = 165872468442
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.
843 : 1, 3, 281, 843
646 : 1, 2, 17, 19, 34, 38, 323, 646
391 : 1, 17, 23, 391
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,646,391,779, is 1.
Now, the common factors can be found like this.
843:3x 281
646:2x 17x 19
391:17x 23
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19 = 323
Therefore, the value for common factors is 323.
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 = 165872468442/(1x323)
LCM = 165872468442/323
LCM = 513537054
Thus, we can understand that the LCM of 843,646,391,779 is 513537054.
