Given numbers are 519,649,638,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 519,649,638,811 is 15843856578.
Find LCM of 519,649,638,811 with Prime Factorization
11 | 519, 649, 638, 811 |
519, 59, 58, 811 |
Multiply the prime numbers at the bottom and the left side.
11 x 519 x 59 x 58 x 811 = 15843856578
Therefore, the lowest common multiple of 519,649,638,811 is 15843856578.
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.
519 x 649 x 638 x 811 = 174282422358
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.
519 : 1, 3, 173, 519
649 : 1, 11, 59, 649
638 : 1, 2, 11, 22, 29, 58, 319, 638
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 519,649,638,811, is 1.
Now, the common factors can be found like this.
519:3x 173
649:11x 59
638:2x 11x 29
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 174282422358/(1x11)
LCM = 174282422358/11
LCM = 15843856578
Thus, we can understand that the LCM of 519,649,638,811 is 15843856578.
