Given numbers are 858,672,100,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,672,100,682 is 74474400.
Find LCM of 858,672,100,682 with Prime Factorization
| 2 | 858, 672, 100, 682 |
| 2 | 429, 336, 50, 341 |
| 3 | 429, 168, 25, 341 |
| 11 | 143, 56, 25, 341 |
| 13, 56, 25, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 56 x 25 x 31 = 74474400
Therefore, the lowest common multiple of 858,672,100,682 is 74474400.
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 672 x 100 x 682 = 39322483200
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
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
682 : 1, 2, 11, 22, 31, 62, 341, 682
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,672,100,682, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
672:2x 2x 2x 2x 2x 3x 7
100:2x 2x 5x 5
682:2x 11x 31
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 39322483200/(2x264)
LCM = 39322483200/528
LCM = 74474400
Thus, we can understand that the LCM of 858,672,100,682 is 74474400.
