Given numbers are 305,264,447,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,264,447,680 is 203957160.
Find LCM of 305,264,447,680 with Prime Factorization
| 2 | 305, 264, 447, 680 |
| 2 | 305, 132, 447, 340 |
| 2 | 305, 66, 447, 170 |
| 3 | 305, 33, 447, 85 |
| 5 | 305, 11, 149, 85 |
| 61, 11, 149, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 61 x 11 x 149 x 17 = 203957160
Therefore, the lowest common multiple of 305,264,447,680 is 203957160.
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.
305 x 264 x 447 x 680 = 24474859200
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.
305 : 1, 5, 61, 305
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
447 : 1, 3, 149, 447
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,264,447,680, is 1.
Now, the common factors can be found like this.
305:5x 61
264:2x 2x 2x 3x 11
447:3x 149
680:2x 2x 2x 5x 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 5 = 120
Therefore, the value for common factors is 120.
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 = 24474859200/(1x120)
LCM = 24474859200/120
LCM = 203957160
Thus, we can understand that the LCM of 305,264,447,680 is 203957160.
