Given numbers are 838,203,460,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,203,460,147 is 821650620.
Find LCM of 838,203,460,147 with Prime Factorization
| 2 | 838, 203, 460, 147 |
| 7 | 419, 203, 230, 147 |
| 419, 29, 230, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 419 x 29 x 230 x 21 = 821650620
Therefore, the lowest common multiple of 838,203,460,147 is 821650620.
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.
838 x 203 x 460 x 147 = 11503108680
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.
838 : 1, 2, 419, 838
203 : 1, 7, 29, 203
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,203,460,147, is 1.
Now, the common factors can be found like this.
838:2x 419
203:7x 29
460:2x 2x 5x 23
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 11503108680/(1x14)
LCM = 11503108680/14
LCM = 821650620
Thus, we can understand that the LCM of 838,203,460,147 is 821650620.
