Find LCM of 904,105,428,819,340 with Prime Factorization
| 2 | 904, 105, 428, 819, 340 |
| 2 | 452, 105, 214, 819, 170 |
| 3 | 226, 105, 107, 819, 85 |
| 5 | 226, 35, 107, 273, 85 |
| 7 | 226, 7, 107, 273, 17 |
| 226, 1, 107, 39, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 226 x 1 x 107 x 39 x 17 = 6733719720
Therefore, the lowest common multiple of 904,105,428,819,340 is 6733719720.
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.
904 x 105 x 428 x 819 x 340 = 11312649129600
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
105 : 1, 3, 5, 7, 15, 21, 35, 105
428 : 1, 2, 4, 107, 214, 428
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,105,428,819,340, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
105:3x 5x 7
428:2x 2x 107
819:3x 3x 7x 13
340:2x 2x 5x 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 2x 2x 2x 3x 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 11312649129600/(1x1680)
LCM = 11312649129600/1680
LCM = 6733719720
Thus, we can understand that the LCM of 904,105,428,819,340 is 6733719720.
