Given numbers are 280,495,308,231,411
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,495,308,231,411 is 3797640.
Find LCM of 280,495,308,231,411 with Prime Factorization
| 2 | 280, 495, 308, 231, 411 |
| 2 | 140, 495, 154, 231, 411 |
| 3 | 70, 495, 77, 231, 411 |
| 5 | 70, 165, 77, 77, 137 |
| 7 | 14, 33, 77, 77, 137 |
| 11 | 2, 33, 11, 11, 137 |
| 2, 3, 1, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 2 x 3 x 1 x 1 x 137 = 3797640
Therefore, the lowest common multiple of 280,495,308,231,411 is 3797640.
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.
280 x 495 x 308 x 231 x 411 = 4052917360800
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
231 : 1, 3, 7, 11, 21, 33, 77, 231
411 : 1, 3, 137, 411
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,495,308,231,411, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
495:3x 3x 5x 11
308:2x 2x 7x 11
231:3x 7x 11
411:3x 137
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 3x 3x 5x 7x 7x 11x 11 = 1067220
Therefore, the value for common factors is 1067220.
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 = 4052917360800/(1x1067220)
LCM = 4052917360800/1067220
LCM = 3797640
Thus, we can understand that the LCM of 280,495,308,231,411 is 3797640.
