Given numbers are 289,680,896,101
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,680,896,101 is 130766720.
Find LCM of 289,680,896,101 with Prime Factorization
| 2 | 289, 680, 896, 101 |
| 2 | 289, 340, 448, 101 |
| 2 | 289, 170, 224, 101 |
| 17 | 289, 85, 112, 101 |
| 17, 5, 112, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 17 x 5 x 112 x 101 = 130766720
Therefore, the lowest common multiple of 289,680,896,101 is 130766720.
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 680 x 896 x 101 = 17784273920
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
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
101 : 1, 101
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,680,896,101, is 1.
Now, the common factors can be found like this.
289:17x 17
680:2x 2x 2x 5x 17
896:2x 2x 2x 2x 2x 2x 2x 7
101:101
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 17 = 136
Therefore, the value for common factors is 136.
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 = 17784273920/(1x136)
LCM = 17784273920/136
LCM = 130766720
Thus, we can understand that the LCM of 289,680,896,101 is 130766720.
