Given numbers are 518,691,842,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,691,842,804 is 60578142996.
Find LCM of 518,691,842,804 with Prime Factorization
| 2 | 518, 691, 842, 804 |
| 259, 691, 421, 402 |
Multiply the prime numbers at the bottom and the left side.
2 x 259 x 691 x 421 x 402 = 60578142996
Therefore, the lowest common multiple of 518,691,842,804 is 60578142996.
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 691 x 842 x 804 = 242312571984
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
691 : 1, 691
842 : 1, 2, 421, 842
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,691,842,804, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
691:691
842:2x 421
804:2x 2x 3x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 242312571984/(1x4)
LCM = 242312571984/4
LCM = 60578142996
Thus, we can understand that the LCM of 518,691,842,804 is 60578142996.
