Given numbers are 557,988,556,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,988,556,858 is 2524299492.
Find LCM of 557,988,556,858 with Prime Factorization
| 2 | 557, 988, 556, 858 |
| 2 | 557, 494, 278, 429 |
| 13 | 557, 247, 139, 429 |
| 557, 19, 139, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 557 x 19 x 139 x 33 = 2524299492
Therefore, the lowest common multiple of 557,988,556,858 is 2524299492.
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.
557 x 988 x 556 x 858 = 262527147168
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.
557 : 1, 557
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
556 : 1, 2, 4, 139, 278, 556
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,988,556,858, is 1.
Now, the common factors can be found like this.
557:557
988:2x 2x 13x 19
556:2x 2x 139
858:2x 3x 11x 13
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 262527147168/(1x104)
LCM = 262527147168/104
LCM = 2524299492
Thus, we can understand that the LCM of 557,988,556,858 is 2524299492.
