Given numbers are 738,838,451,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,838,451,867 is 983016738.
Find LCM of 738,838,451,867 with Prime Factorization
| 2 | 738, 838, 451, 867 |
| 3 | 369, 419, 451, 867 |
| 41 | 123, 419, 451, 289 |
| 3, 419, 11, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 3 x 419 x 11 x 289 = 983016738
Therefore, the lowest common multiple of 738,838,451,867 is 983016738.
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.
738 x 838 x 451 x 867 = 241822117548
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
838 : 1, 2, 419, 838
451 : 1, 11, 41, 451
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,838,451,867, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
838:2x 419
451:11x 41
867:3x 17x 17
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 41 = 246
Therefore, the value for common factors is 246.
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 = 241822117548/(1x246)
LCM = 241822117548/246
LCM = 983016738
Thus, we can understand that the LCM of 738,838,451,867 is 983016738.
