Given numbers are 873,638,983,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,638,983,261 is 547505442.
Find LCM of 873,638,983,261 with Prime Factorization
| 3 | 873, 638, 983, 261 |
| 3 | 291, 638, 983, 87 |
| 29 | 97, 638, 983, 29 |
| 97, 22, 983, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 97 x 22 x 983 x 1 = 547505442
Therefore, the lowest common multiple of 873,638,983,261 is 547505442.
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.
873 x 638 x 983 x 261 = 142898920362
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.
873 : 1, 3, 9, 97, 291, 873
638 : 1, 2, 11, 22, 29, 58, 319, 638
983 : 1, 983
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,638,983,261, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
638:2x 11x 29
983:983
261:3x 3x 29
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 29 = 261
Therefore, the value for common factors is 261.
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 = 142898920362/(1x261)
LCM = 142898920362/261
LCM = 547505442
Thus, we can understand that the LCM of 873,638,983,261 is 547505442.
