Given numbers are 820,403,858,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,403,858,696 is 632500440.
Find LCM of 820,403,858,696 with Prime Factorization
| 2 | 820, 403, 858, 696 |
| 2 | 410, 403, 429, 348 |
| 3 | 205, 403, 429, 174 |
| 13 | 205, 403, 143, 58 |
| 205, 31, 11, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 205 x 31 x 11 x 58 = 632500440
Therefore, the lowest common multiple of 820,403,858,696 is 632500440.
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.
820 x 403 x 858 x 696 = 197340137280
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
403 : 1, 13, 31, 403
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,403,858,696, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
403:13x 31
858:2x 3x 11x 13
696:2x 2x 2x 3x 29
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 13 = 312
Therefore, the value for common factors is 312.
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 = 197340137280/(1x312)
LCM = 197340137280/312
LCM = 632500440
Thus, we can understand that the LCM of 820,403,858,696 is 632500440.
