Given numbers are 523,720,382,698,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 523,720,382,698,905 is 4543301460240.
Find LCM of 523,720,382,698,905 with Prime Factorization
| 2 | 523, 720, 382, 698, 905 |
| 5 | 523, 360, 191, 349, 905 |
| 523, 72, 191, 349, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 523 x 72 x 191 x 349 x 181 = 4543301460240
Therefore, the lowest common multiple of 523,720,382,698,905 is 4543301460240.
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.
523 x 720 x 382 x 698 x 905 = 90866029204800
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.
523 : 1, 523
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
382 : 1, 2, 191, 382
698 : 1, 2, 349, 698
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,720,382,698,905, is 1.
Now, the common factors can be found like this.
523:523
720:2x 2x 2x 2x 3x 3x 5
382:2x 191
698:2x 349
905:5x 181
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 5 = 20
Therefore, the value for common factors is 20.
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 = 90866029204800/(1x20)
LCM = 90866029204800/20
LCM = 4543301460240
Thus, we can understand that the LCM of 523,720,382,698,905 is 4543301460240.
