Given numbers are 401,806,561,834,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,806,561,834,425 is 630082016850.
Find LCM of 401,806,561,834,425 with Prime Factorization
| 2 | 401, 806, 561, 834, 425 |
| 3 | 401, 403, 561, 417, 425 |
| 17 | 401, 403, 187, 139, 425 |
| 401, 403, 11, 139, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 401 x 403 x 11 x 139 x 25 = 630082016850
Therefore, the lowest common multiple of 401,806,561,834,425 is 630082016850.
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.
401 x 806 x 561 x 834 x 425 = 64268365718700
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.
401 : 1, 401
806 : 1, 2, 13, 26, 31, 62, 403, 806
561 : 1, 3, 11, 17, 33, 51, 187, 561
834 : 1, 2, 3, 6, 139, 278, 417, 834
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,806,561,834,425, is 1.
Now, the common factors can be found like this.
401:401
806:2x 13x 31
561:3x 11x 17
834:2x 3x 139
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 64268365718700/(1x102)
LCM = 64268365718700/102
LCM = 630082016850
Thus, we can understand that the LCM of 401,806,561,834,425 is 630082016850.
