Find LCM of 828,646,102,775,342 with Prime Factorization
| 2 | 828, 646, 102, 775, 342 |
| 3 | 414, 323, 51, 775, 171 |
| 3 | 138, 323, 17, 775, 57 |
| 17 | 46, 323, 17, 775, 19 |
| 19 | 46, 19, 1, 775, 19 |
| 46, 1, 1, 775, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 19 x 46 x 1 x 1 x 775 x 1 = 207269100
Therefore, the lowest common multiple of 828,646,102,775,342 is 207269100.
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.
828 x 646 x 102 x 775 x 342 = 14460750568800
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
646 : 1, 2, 17, 19, 34, 38, 323, 646
102 : 1, 2, 3, 6, 17, 34, 51, 102
775 : 1, 5, 25, 31, 155, 775
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,646,102,775,342, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
646:2x 17x 19
102:2x 3x 17
775:5x 5x 31
342:2x 3x 3x 19
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 3x 3x 17x 19 = 69768
Therefore, the value for common factors is 69768.
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 = 14460750568800/(1x69768)
LCM = 14460750568800/69768
LCM = 207269100
Thus, we can understand that the LCM of 828,646,102,775,342 is 207269100.
