Find LCM of 578,648,856,837,918 with Prime Factorization
| 2 | 578, 648, 856, 837, 918 |
| 2 | 289, 324, 428, 837, 459 |
| 2 | 289, 162, 214, 837, 459 |
| 3 | 289, 81, 107, 837, 459 |
| 3 | 289, 27, 107, 279, 153 |
| 3 | 289, 9, 107, 93, 51 |
| 17 | 289, 3, 107, 31, 17 |
| 1, 3, 107, 31, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 17 x 1 x 3 x 107 x 31 x 17 = 621181224
Therefore, the lowest common multiple of 578,648,856,837,918 is 621181224.
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.
578 x 648 x 856 x 837 x 918 = 246345565089024
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.
578 : 1, 2, 17, 34, 289, 578
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
856 : 1, 2, 4, 8, 107, 214, 428, 856
837 : 1, 3, 9, 27, 31, 93, 279, 837
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,648,856,837,918, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
648:2x 2x 2x 3x 3x 3x 3
856:2x 2x 2x 107
837:3x 3x 3x 31
918:2x 3x 3x 3x 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 2x 3x 3x 3x 3x 3x 3x 17 = 396576
Therefore, the value for common factors is 396576.
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 = 246345565089024/(1x396576)
LCM = 246345565089024/396576
LCM = 621181224
Thus, we can understand that the LCM of 578,648,856,837,918 is 621181224.
