Given numbers are 220,978,898,873
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,978,898,873 is 14056295220.
Find LCM of 220,978,898,873 with Prime Factorization
| 2 | 220, 978, 898, 873 |
| 3 | 110, 489, 449, 873 |
| 110, 163, 449, 291 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 110 x 163 x 449 x 291 = 14056295220
Therefore, the lowest common multiple of 220,978,898,873 is 14056295220.
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.
220 x 978 x 898 x 873 = 168675542640
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
978 : 1, 2, 3, 6, 163, 326, 489, 978
898 : 1, 2, 449, 898
873 : 1, 3, 9, 97, 291, 873
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,978,898,873, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
978:2x 3x 163
898:2x 449
873:3x 3x 97
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 3 = 12
Therefore, the value for common factors is 12.
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 = 168675542640/(1x12)
LCM = 168675542640/12
LCM = 14056295220
Thus, we can understand that the LCM of 220,978,898,873 is 14056295220.
