Find LCM of 408,496,758,512,840 with Prime Factorization
| 2 | 408, 496, 758, 512, 840 |
| 2 | 204, 248, 379, 256, 420 |
| 2 | 102, 124, 379, 128, 210 |
| 2 | 51, 62, 379, 64, 105 |
| 3 | 51, 31, 379, 32, 105 |
| 17, 31, 379, 32, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 31 x 379 x 32 x 35 = 10737646080
Therefore, the lowest common multiple of 408,496,758,512,840 is 10737646080.
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.
408 x 496 x 758 x 512 x 840 = 65972097515520
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
758 : 1, 2, 379, 758
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,496,758,512,840, is 2.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
496:2x 2x 2x 2x 31
758:2x 379
512:2x 2x 2x 2x 2x 2x 2x 2x 2
840:2x 2x 2x 3x 5x 7
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 2x 2x 2x 2x 2x 3 = 3072
Therefore, the value for common factors is 3072.
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 = 65972097515520/(2x3072)
LCM = 65972097515520/6144
LCM = 10737646080
Thus, we can understand that the LCM of 408,496,758,512,840 is 10737646080.
