Given numbers are 280,461,205,395,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,461,205,395,310 is 12960793720.
Find LCM of 280,461,205,395,310 with Prime Factorization
2 | 280, 461, 205, 395, 310 |
5 | 140, 461, 205, 395, 155 |
28, 461, 41, 79, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 28 x 461 x 41 x 79 x 31 = 12960793720
Therefore, the lowest common multiple of 280,461,205,395,310 is 12960793720.
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 461 x 205 x 395 x 310 = 3240198430000
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
461 : 1, 461
205 : 1, 5, 41, 205
395 : 1, 5, 79, 395
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,461,205,395,310, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
461:461
205:5x 41
395:5x 79
310:2x 5x 31
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 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 3240198430000/(1x250)
LCM = 3240198430000/250
LCM = 12960793720
Thus, we can understand that the LCM of 280,461,205,395,310 is 12960793720.
