Find LCM of 123,306,958,927,721 with Prime Factorization
| 2 | 123, 306, 958, 927, 721 |
| 3 | 123, 153, 479, 927, 721 |
| 3 | 41, 51, 479, 309, 721 |
| 103 | 41, 17, 479, 103, 721 |
| 41, 17, 479, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 103 x 41 x 17 x 479 x 1 x 7 = 4332874014
Therefore, the lowest common multiple of 123,306,958,927,721 is 4332874014.
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.
123 x 306 x 958 x 927 x 721 = 24099445265868
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.
123 : 1, 3, 41, 123
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
958 : 1, 2, 479, 958
927 : 1, 3, 9, 103, 309, 927
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,306,958,927,721, is 1.
Now, the common factors can be found like this.
123:3x 41
306:2x 3x 3x 17
958:2x 479
927:3x 3x 103
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 103 = 5562
Therefore, the value for common factors is 5562.
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 = 24099445265868/(1x5562)
LCM = 24099445265868/5562
LCM = 4332874014
Thus, we can understand that the LCM of 123,306,958,927,721 is 4332874014.
