Find LCM of 331,752,520,649,815 with Prime Factorization
| 2 | 331, 752, 520, 649, 815 |
| 2 | 331, 376, 260, 649, 815 |
| 2 | 331, 188, 130, 649, 815 |
| 5 | 331, 94, 65, 649, 815 |
| 331, 94, 13, 649, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 331 x 94 x 13 x 649 x 163 = 1711557493360
Therefore, the lowest common multiple of 331,752,520,649,815 is 1711557493360.
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.
331 x 752 x 520 x 649 x 815 = 68462299734400
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.
331 : 1, 331
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
649 : 1, 11, 59, 649
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,752,520,649,815, is 1.
Now, the common factors can be found like this.
331:331
752:2x 2x 2x 2x 47
520:2x 2x 2x 5x 13
649:11x 59
815:5x 163
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 5 = 40
Therefore, the value for common factors is 40.
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 = 68462299734400/(1x40)
LCM = 68462299734400/40
LCM = 1711557493360
Thus, we can understand that the LCM of 331,752,520,649,815 is 1711557493360.
