Find LCM of 858,969,351,748 with Prime Factorization
| 2 | 858, 969, 351, 748 |
| 3 | 429, 969, 351, 374 |
| 11 | 143, 323, 117, 374 |
| 13 | 13, 323, 117, 34 |
| 17 | 1, 323, 9, 34 |
| 1, 19, 9, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 17 x 1 x 19 x 9 x 2 = 4988412
Therefore, the lowest common multiple of 858,969,351,748 is 4988412.
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 969 x 351 x 748 = 218282932296
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
969 : 1, 3, 17, 19, 51, 57, 323, 969
351 : 1, 3, 9, 13, 27, 39, 117, 351
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,969,351,748, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
969:3x 17x 19
351:3x 3x 3x 13
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 13x 17 = 43758
Therefore, the value for common factors is 43758.
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 = 218282932296/(1x43758)
LCM = 218282932296/43758
LCM = 4988412
Thus, we can understand that the LCM of 858,969,351,748 is 4988412.
