Given numbers are 525,721,645,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 525,721,645,813 is 630135975.
Find LCM of 525,721,645,813 with Prime Factorization
| 3 | 525, 721, 645, 813 |
| 5 | 175, 721, 215, 271 |
| 7 | 35, 721, 43, 271 |
| 5, 103, 43, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 5 x 103 x 43 x 271 = 630135975
Therefore, the lowest common multiple of 525,721,645,813 is 630135975.
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.
525 x 721 x 645 x 813 = 198492832125
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
721 : 1, 7, 103, 721
645 : 1, 3, 5, 15, 43, 129, 215, 645
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,721,645,813, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
721:7x 103
645:3x 5x 43
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 198492832125/(1x315)
LCM = 198492832125/315
LCM = 630135975
Thus, we can understand that the LCM of 525,721,645,813 is 630135975.
