Given numbers are 545,830,489,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,830,489,163 is 44239830.
Find LCM of 545,830,489,163 with Prime Factorization
| 5 | 545, 830, 489, 163 |
| 163 | 109, 166, 489, 163 |
| 109, 166, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 163 x 109 x 166 x 3 x 1 = 44239830
Therefore, the lowest common multiple of 545,830,489,163 is 44239830.
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.
545 x 830 x 489 x 163 = 36055461450
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.
545 : 1, 5, 109, 545
830 : 1, 2, 5, 10, 83, 166, 415, 830
489 : 1, 3, 163, 489
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,830,489,163, is 1.
Now, the common factors can be found like this.
545:5x 109
830:2x 5x 83
489:3x 163
163:163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 163 = 815
Therefore, the value for common factors is 815.
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 = 36055461450/(1x815)
LCM = 36055461450/815
LCM = 44239830
Thus, we can understand that the LCM of 545,830,489,163 is 44239830.
