Given numbers are 815,664,622,419
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,664,622,419 is 70518018440.
Find LCM of 815,664,622,419 with Prime Factorization
| 2 | 815, 664, 622, 419 |
| 815, 332, 311, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 815 x 332 x 311 x 419 = 70518018440
Therefore, the lowest common multiple of 815,664,622,419 is 70518018440.
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.
815 x 664 x 622 x 419 = 141036036880
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.
815 : 1, 5, 163, 815
664 : 1, 2, 4, 8, 83, 166, 332, 664
622 : 1, 2, 311, 622
419 : 1, 419
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,664,622,419, is 1.
Now, the common factors can be found like this.
815:5x 163
664:2x 2x 2x 83
622:2x 311
419:419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 141036036880/(1x2)
LCM = 141036036880/2
LCM = 70518018440
Thus, we can understand that the LCM of 815,664,622,419 is 70518018440.
