Given numbers are 803,969,144,279,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,969,144,279,649 is 68311569744.
Find LCM of 803,969,144,279,649 with Prime Factorization
| 3 | 803, 969, 144, 279, 649 |
| 3 | 803, 323, 48, 93, 649 |
| 11 | 803, 323, 16, 31, 649 |
| 73, 323, 16, 31, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 73 x 323 x 16 x 31 x 59 = 68311569744
Therefore, the lowest common multiple of 803,969,144,279,649 is 68311569744.
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.
803 x 969 x 144 x 279 x 649 = 20288536213968
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.
803 : 1, 11, 73, 803
969 : 1, 3, 17, 19, 51, 57, 323, 969
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
279 : 1, 3, 9, 31, 93, 279
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,969,144,279,649, is 1.
Now, the common factors can be found like this.
803:11x 73
969:3x 17x 19
144:2x 2x 2x 2x 3x 3
279:3x 3x 31
649:11x 59
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 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 20288536213968/(1x297)
LCM = 20288536213968/297
LCM = 68311569744
Thus, we can understand that the LCM of 803,969,144,279,649 is 68311569744.
