Given numbers are 483,813,969,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 483,813,969,138 is 84556878.
Find LCM of 483,813,969,138 with Prime Factorization
| 3 | 483, 813, 969, 138 |
| 23 | 161, 271, 323, 46 |
| 7, 271, 323, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 7 x 271 x 323 x 2 = 84556878
Therefore, the lowest common multiple of 483,813,969,138 is 84556878.
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.
483 x 813 x 969 x 138 = 52509821238
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.
483 : 1, 3, 7, 21, 23, 69, 161, 483
813 : 1, 3, 271, 813
969 : 1, 3, 17, 19, 51, 57, 323, 969
138 : 1, 2, 3, 6, 23, 46, 69, 138
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 483,813,969,138, is 3.
Now, the common factors can be found like this.
483:3x 7x 23
813:3x 271
969:3x 17x 19
138:2x 3x 23
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 23 = 207
Therefore, the value for common factors is 207.
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 = 52509821238/(3x207)
LCM = 52509821238/621
LCM = 84556878
Thus, we can understand that the LCM of 483,813,969,138 is 84556878.
