Given numbers are 834,561,635,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,561,635,389 is 38523965370.
Find LCM of 834,561,635,389 with Prime Factorization
| 3 | 834, 561, 635, 389 |
| 278, 187, 635, 389 |
Multiply the prime numbers at the bottom and the left side.
3 x 278 x 187 x 635 x 389 = 38523965370
Therefore, the lowest common multiple of 834,561,635,389 is 38523965370.
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.
834 x 561 x 635 x 389 = 115571896110
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
561 : 1, 3, 11, 17, 33, 51, 187, 561
635 : 1, 5, 127, 635
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,561,635,389, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
561:3x 11x 17
635:5x 127
389:389
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 = 115571896110/(1x3)
LCM = 115571896110/3
LCM = 38523965370
Thus, we can understand that the LCM of 834,561,635,389 is 38523965370.
