Given numbers are 518,496,775,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,496,775,638 is 1024500400.
Find LCM of 518,496,775,638 with Prime Factorization
2 | 518, 496, 775, 638 |
31 | 259, 248, 775, 319 |
259, 8, 25, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 259 x 8 x 25 x 319 = 1024500400
Therefore, the lowest common multiple of 518,496,775,638 is 1024500400.
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 496 x 775 x 638 = 127038049600
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
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
775 : 1, 5, 25, 31, 155, 775
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,496,775,638, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
496:2x 2x 2x 2x 31
775:5x 5x 31
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 31 = 124
Therefore, the value for common factors is 124.
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 = 127038049600/(1x124)
LCM = 127038049600/124
LCM = 1024500400
Thus, we can understand that the LCM of 518,496,775,638 is 1024500400.
