Given numbers are 489,851,161,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,851,161,917 is 381599463.
Find LCM of 489,851,161,917 with Prime Factorization
| 7 | 489, 851, 161, 917 |
| 23 | 489, 851, 23, 131 |
| 489, 37, 1, 131 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 489 x 37 x 1 x 131 = 381599463
Therefore, the lowest common multiple of 489,851,161,917 is 381599463.
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.
489 x 851 x 161 x 917 = 61437513543
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.
489 : 1, 3, 163, 489
851 : 1, 23, 37, 851
161 : 1, 7, 23, 161
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,851,161,917, is 1.
Now, the common factors can be found like this.
489:3x 163
851:23x 37
161:7x 23
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 61437513543/(1x161)
LCM = 61437513543/161
LCM = 381599463
Thus, we can understand that the LCM of 489,851,161,917 is 381599463.
