Given numbers are 518,867,649,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,867,649,441 is 6120865674.
Find LCM of 518,867,649,441 with Prime Factorization
| 3 | 518, 867, 649, 441 |
| 7 | 518, 289, 649, 147 |
| 74, 289, 649, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 74 x 289 x 649 x 21 = 6120865674
Therefore, the lowest common multiple of 518,867,649,441 is 6120865674.
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.
518 x 867 x 649 x 441 = 128538179154
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
867 : 1, 3, 17, 51, 289, 867
649 : 1, 11, 59, 649
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,867,649,441, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
867:3x 17x 17
649:11x 59
441:3x 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.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 128538179154/(1x21)
LCM = 128538179154/21
LCM = 6120865674
Thus, we can understand that the LCM of 518,867,649,441 is 6120865674.
