Given numbers are 561,830,844,368
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,830,844,368 is 18077619120.
Find LCM of 561,830,844,368 with Prime Factorization
| 2 | 561, 830, 844, 368 |
| 2 | 561, 415, 422, 184 |
| 561, 415, 211, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 561 x 415 x 211 x 92 = 18077619120
Therefore, the lowest common multiple of 561,830,844,368 is 18077619120.
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 830 x 844 x 368 = 144620952960
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
830 : 1, 2, 5, 10, 83, 166, 415, 830
844 : 1, 2, 4, 211, 422, 844
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,830,844,368, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
830:2x 5x 83
844:2x 2x 211
368:2x 2x 2x 2x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 144620952960/(1x8)
LCM = 144620952960/8
LCM = 18077619120
Thus, we can understand that the LCM of 561,830,844,368 is 18077619120.
