Given numbers are 838,540,525,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,540,525,747 is 657285300.
Find LCM of 838,540,525,747 with Prime Factorization
| 2 | 838, 540, 525, 747 |
| 3 | 419, 270, 525, 747 |
| 3 | 419, 90, 175, 249 |
| 5 | 419, 30, 175, 83 |
| 419, 6, 35, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 419 x 6 x 35 x 83 = 657285300
Therefore, the lowest common multiple of 838,540,525,747 is 657285300.
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 540 x 525 x 747 = 177467031000
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
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,540,525,747, is 1.
Now, the common factors can be found like this.
838:2x 419
540:2x 2x 3x 3x 3x 5
525:3x 5x 5x 7
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 177467031000/(1x270)
LCM = 177467031000/270
LCM = 657285300
Thus, we can understand that the LCM of 838,540,525,747 is 657285300.
