Given numbers are 561,143,741,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,143,741,671 is 8452587.
Find LCM of 561,143,741,671 with Prime Factorization
| 3 | 561, 143, 741, 671 |
| 11 | 187, 143, 247, 671 |
| 13 | 17, 13, 247, 61 |
| 17, 1, 19, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 17 x 1 x 19 x 61 = 8452587
Therefore, the lowest common multiple of 561,143,741,671 is 8452587.
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.
561 x 143 x 741 x 671 = 39887758053
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
143 : 1, 11, 13, 143
741 : 1, 3, 13, 19, 39, 57, 247, 741
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,143,741,671, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
143:11x 13
741:3x 13x 19
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 13 = 4719
Therefore, the value for common factors is 4719.
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 = 39887758053/(1x4719)
LCM = 39887758053/4719
LCM = 8452587
Thus, we can understand that the LCM of 561,143,741,671 is 8452587.
