Given numbers are 844,720,644,146,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,720,644,146,506 is 19640673360.
Find LCM of 844,720,644,146,506 with Prime Factorization
| 2 | 844, 720, 644, 146, 506 |
| 2 | 422, 360, 322, 73, 253 |
| 23 | 211, 180, 161, 73, 253 |
| 211, 180, 7, 73, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 211 x 180 x 7 x 73 x 11 = 19640673360
Therefore, the lowest common multiple of 844,720,644,146,506 is 19640673360.
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 720 x 644 x 146 x 506 = 28911071185920
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
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
146 : 1, 2, 73, 146
506 : 1, 2, 11, 22, 23, 46, 253, 506
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,720,644,146,506, is 2.
Now, the common factors can be found like this.
844:2x 2x 211
720:2x 2x 2x 2x 3x 3x 5
644:2x 2x 7x 23
146:2x 73
506:2x 11x 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 2x 2x 2x 23 = 736
Therefore, the value for common factors is 736.
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 = 28911071185920/(2x736)
LCM = 28911071185920/1472
LCM = 19640673360
Thus, we can understand that the LCM of 844,720,644,146,506 is 19640673360.
