Given numbers are 420,843,363,916,633
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,843,363,916,633 is 690015613980.
Find LCM of 420,843,363,916,633 with Prime Factorization
| 2 | 420, 843, 363, 916, 633 |
| 2 | 210, 843, 363, 458, 633 |
| 3 | 105, 843, 363, 229, 633 |
| 35, 281, 121, 229, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 35 x 281 x 121 x 229 x 211 = 690015613980
Therefore, the lowest common multiple of 420,843,363,916,633 is 690015613980.
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.
420 x 843 x 363 x 916 x 633 = 74521686309840
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
843 : 1, 3, 281, 843
363 : 1, 3, 11, 33, 121, 363
916 : 1, 2, 4, 229, 458, 916
633 : 1, 3, 211, 633
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,843,363,916,633, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
843:3x 281
363:3x 11x 11
916:2x 2x 229
633:3x 211
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 74521686309840/(1x108)
LCM = 74521686309840/108
LCM = 690015613980
Thus, we can understand that the LCM of 420,843,363,916,633 is 690015613980.
