Find LCM of 289,867,680,928,778 with Prime Factorization
| 2 | 289, 867, 680, 928, 778 |
| 2 | 289, 867, 340, 464, 389 |
| 2 | 289, 867, 170, 232, 389 |
| 17 | 289, 867, 85, 116, 389 |
| 17 | 17, 51, 5, 116, 389 |
| 1, 3, 5, 116, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 17 x 1 x 3 x 5 x 116 x 389 = 1564900320
Therefore, the lowest common multiple of 289,867,680,928,778 is 1564900320.
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.
289 x 867 x 680 x 928 x 778 = 123013684354560
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.
289 : 1, 17, 289
867 : 1, 3, 17, 51, 289, 867
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,867,680,928,778, is 1.
Now, the common factors can be found like this.
289:17x 17
867:3x 17x 17
680:2x 2x 2x 5x 17
928:2x 2x 2x 2x 2x 29
778:2x 389
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 17x 17x 17 = 78608
Therefore, the value for common factors is 78608.
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 = 123013684354560/(1x78608)
LCM = 123013684354560/78608
LCM = 1564900320
Thus, we can understand that the LCM of 289,867,680,928,778 is 1564900320.
