Find LCM of 749,648,496,682,285 with Prime Factorization
| 2 | 749, 648, 496, 682, 285 |
| 2 | 749, 324, 248, 341, 285 |
| 2 | 749, 162, 124, 341, 285 |
| 3 | 749, 81, 62, 341, 285 |
| 31 | 749, 27, 62, 341, 95 |
| 749, 27, 2, 11, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 31 x 749 x 27 x 2 x 11 x 95 = 31445956080
Therefore, the lowest common multiple of 749,648,496,682,285 is 31445956080.
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.
749 x 648 x 496 x 682 x 285 = 46791582647040
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.
749 : 1, 7, 107, 749
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
682 : 1, 2, 11, 22, 31, 62, 341, 682
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,648,496,682,285, is 1.
Now, the common factors can be found like this.
749:7x 107
648:2x 2x 2x 3x 3x 3x 3
496:2x 2x 2x 2x 31
682:2x 11x 31
285:3x 5x 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 2x 3x 31 = 1488
Therefore, the value for common factors is 1488.
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 = 46791582647040/(1x1488)
LCM = 46791582647040/1488
LCM = 31445956080
Thus, we can understand that the LCM of 749,648,496,682,285 is 31445956080.
