Given numbers are 844,503,856,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,503,856,642 is 272549544.
Find LCM of 844,503,856,642 with Prime Factorization
| 2 | 844, 503, 856, 642 |
| 2 | 422, 503, 428, 321 |
| 107 | 211, 503, 214, 321 |
| 211, 503, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 211 x 503 x 2 x 3 = 272549544
Therefore, the lowest common multiple of 844,503,856,642 is 272549544.
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.
844 x 503 x 856 x 642 = 233302409664
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.
844 : 1, 2, 4, 211, 422, 844
503 : 1, 503
856 : 1, 2, 4, 8, 107, 214, 428, 856
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,503,856,642, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
503:503
856:2x 2x 2x 107
642:2x 3x 107
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 2x 107 = 856
Therefore, the value for common factors is 856.
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 = 233302409664/(1x856)
LCM = 233302409664/856
LCM = 272549544
Thus, we can understand that the LCM of 844,503,856,642 is 272549544.
