Given numbers are 656,339,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,339,858 is 31800912.
Find LCM of 656,339,858 with Prime Factorization
| 2 | 656, 339, 858 |
| 3 | 328, 339, 429 |
| 328, 113, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 328 x 113 x 143 = 31800912
Therefore, the lowest common multiple of 656,339,858 is 31800912.
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.
656 x 339 x 858 = 190805472
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
339 : 1, 3, 113, 339
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 656,339,858, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
339:3x 113
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 3 = 6
Therefore, the value for common factors is 6.
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 = 190805472/(1x6)
LCM = 190805472/6
LCM = 31800912
Thus, we can understand that the LCM of 656,339,858 is 31800912.
