Given numbers are 260,650,447,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,650,447,289 is 167937900.
Find LCM of 260,650,447,289 with Prime Factorization
| 2 | 260, 650, 447, 289 |
| 5 | 130, 325, 447, 289 |
| 13 | 26, 65, 447, 289 |
| 2, 5, 447, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 2 x 5 x 447 x 289 = 167937900
Therefore, the lowest common multiple of 260,650,447,289 is 167937900.
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.
260 x 650 x 447 x 289 = 21831927000
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
447 : 1, 3, 149, 447
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,650,447,289, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
650:2x 5x 5x 13
447:3x 149
289:17x 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 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 21831927000/(1x130)
LCM = 21831927000/130
LCM = 167937900
Thus, we can understand that the LCM of 260,650,447,289 is 167937900.
