Find LCM of 758,486,672,280,985 with Prime Factorization
| 2 | 758, 486, 672, 280, 985 |
| 2 | 379, 243, 336, 140, 985 |
| 2 | 379, 243, 168, 70, 985 |
| 3 | 379, 243, 84, 35, 985 |
| 5 | 379, 81, 28, 35, 985 |
| 7 | 379, 81, 28, 7, 197 |
| 379, 81, 4, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 379 x 81 x 4 x 1 x 197 = 20320282080
Therefore, the lowest common multiple of 758,486,672,280,985 is 20320282080.
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.
758 x 486 x 672 x 280 x 985 = 68276147788800
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.
758 : 1, 2, 379, 758
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,486,672,280,985, is 1.
Now, the common factors can be found like this.
758:2x 379
486:2x 3x 3x 3x 3x 3
672:2x 2x 2x 2x 2x 3x 7
280:2x 2x 2x 5x 7
985:5x 197
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 5x 7 = 3360
Therefore, the value for common factors is 3360.
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 = 68276147788800/(1x3360)
LCM = 68276147788800/3360
LCM = 20320282080
Thus, we can understand that the LCM of 758,486,672,280,985 is 20320282080.
