The LCM of 561,871,408,363 is 42999528.
Find LCM of 561,871,408,363 with Prime Factorization
| 3 | 561, 871, 408, 363 |
| 11 | 187, 871, 136, 121 |
| 17 | 17, 871, 136, 11 |
| 1, 871, 8, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 1 x 871 x 8 x 11 = 42999528
Therefore, the lowest common multiple of 561,871,408,363 is 42999528.
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 871 x 408 x 363 = 72368205624
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
871 : 1, 13, 67, 871
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
363 : 1, 3, 11, 33, 121, 363
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,871,408,363, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
871:13x 67
408:2x 2x 2x 3x 17
363:3x 11x 11
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 11x 17 = 1683
Therefore, the value for common factors is 1683.
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 = 72368205624/(1x1683)
LCM = 72368205624/1683
LCM = 42999528
Thus, we can understand that the LCM of 561,871,408,363 is 42999528.
