Given numbers are 813,551,469,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,551,469,938 is 420189294.
Find LCM of 813,551,469,938 with Prime Factorization
| 7 | 813, 551, 469, 938 |
| 67 | 813, 551, 67, 134 |
| 813, 551, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 67 x 813 x 551 x 1 x 2 = 420189294
Therefore, the lowest common multiple of 813,551,469,938 is 420189294.
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.
813 x 551 x 469 x 938 = 197068778886
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.
813 : 1, 3, 271, 813
551 : 1, 19, 29, 551
469 : 1, 7, 67, 469
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,551,469,938, is 1.
Now, the common factors can be found like this.
813:3x 271
551:19x 29
469:7x 67
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 67 = 469
Therefore, the value for common factors is 469.
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 = 197068778886/(1x469)
LCM = 197068778886/469
LCM = 420189294
Thus, we can understand that the LCM of 813,551,469,938 is 420189294.
