The LCM of 578,768,153,612 is 665856.
Find LCM of 578,768,153,612 with Prime Factorization
| 2 | 578, 768, 153, 612 |
| 2 | 289, 384, 153, 306 |
| 3 | 289, 192, 153, 153 |
| 3 | 289, 64, 51, 51 |
| 17 | 289, 64, 17, 17 |
| 1, 64, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 1 x 64 x 1 x 17 = 665856
Therefore, the lowest common multiple of 578,768,153,612 is 665856.
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 768 x 153 x 612 = 41565394944
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
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
153 : 1, 3, 9, 17, 51, 153
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,768,153,612, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
153:3x 3x 17
612:2x 2x 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 3x 3x 3x 17x 17 = 62424
Therefore, the value for common factors is 62424.
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 = 41565394944/(1x62424)
LCM = 41565394944/62424
LCM = 665856
Thus, we can understand that the LCM of 578,768,153,612 is 665856.
