Given numbers are 858,470,788,530,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,470,788,530,121 is 46314814260.
Find LCM of 858,470,788,530,121 with Prime Factorization
| 2 | 858, 470, 788, 530, 121 |
| 5 | 429, 235, 394, 265, 121 |
| 11 | 429, 47, 394, 53, 121 |
| 39, 47, 394, 53, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 39 x 47 x 394 x 53 x 11 = 46314814260
Therefore, the lowest common multiple of 858,470,788,530,121 is 46314814260.
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.
858 x 470 x 788 x 530 x 121 = 20378518274400
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
470 : 1, 2, 5, 10, 47, 94, 235, 470
788 : 1, 2, 4, 197, 394, 788
530 : 1, 2, 5, 10, 53, 106, 265, 530
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,470,788,530,121, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
470:2x 5x 47
788:2x 2x 197
530:2x 5x 53
121:11x 11
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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 20378518274400/(1x440)
LCM = 20378518274400/440
LCM = 46314814260
Thus, we can understand that the LCM of 858,470,788,530,121 is 46314814260.
