Given numbers are 858,661,966,882
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,661,966,882 is 1917493578.
Find LCM of 858,661,966,882 with Prime Factorization
| 2 | 858, 661, 966, 882 |
| 3 | 429, 661, 483, 441 |
| 7 | 143, 661, 161, 147 |
| 143, 661, 23, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 143 x 661 x 23 x 21 = 1917493578
Therefore, the lowest common multiple of 858,661,966,882 is 1917493578.
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 661 x 966 x 882 = 483208381656
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
661 : 1, 661
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,661,966,882, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
661:661
966:2x 3x 7x 23
882:2x 3x 3x 7x 7
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 483208381656/(1x252)
LCM = 483208381656/252
LCM = 1917493578
Thus, we can understand that the LCM of 858,661,966,882 is 1917493578.
