Given numbers are 725,738,861,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,738,861,841 is 108615150.
Find LCM of 725,738,861,841 with Prime Factorization
| 3 | 725, 738, 861, 841 |
| 29 | 725, 246, 287, 841 |
| 41 | 25, 246, 287, 29 |
| 25, 6, 7, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 41 x 25 x 6 x 7 x 29 = 108615150
Therefore, the lowest common multiple of 725,738,861,841 is 108615150.
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.
725 x 738 x 861 x 841 = 387430240050
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.
725 : 1, 5, 25, 29, 145, 725
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
861 : 1, 3, 7, 21, 41, 123, 287, 861
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,738,861,841, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
738:2x 3x 3x 41
861:3x 7x 41
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 29x 41 = 3567
Therefore, the value for common factors is 3567.
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 = 387430240050/(1x3567)
LCM = 387430240050/3567
LCM = 108615150
Thus, we can understand that the LCM of 725,738,861,841 is 108615150.
