Find LCM of 378,803,869,858,546 with Prime Factorization
| 2 | 378, 803, 869, 858, 546 |
| 3 | 189, 803, 869, 429, 273 |
| 7 | 63, 803, 869, 143, 91 |
| 11 | 9, 803, 869, 143, 13 |
| 13 | 9, 73, 79, 13, 13 |
| 9, 73, 79, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 13 x 9 x 73 x 79 x 1 x 1 = 311729418
Therefore, the lowest common multiple of 378,803,869,858,546 is 311729418.
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.
378 x 803 x 869 x 858 x 546 = 123568294377528
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
803 : 1, 11, 73, 803
869 : 1, 11, 79, 869
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,803,869,858,546, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
803:11x 73
869:11x 79
858:2x 3x 11x 13
546:2x 3x 7x 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 2x 3x 3x 7x 11x 11x 13 = 396396
Therefore, the value for common factors is 396396.
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 = 123568294377528/(1x396396)
LCM = 123568294377528/396396
LCM = 311729418
Thus, we can understand that the LCM of 378,803,869,858,546 is 311729418.
