Given numbers are 309,981,380,604,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,981,380,604,280 is 81169862760.
Find LCM of 309,981,380,604,280 with Prime Factorization
| 2 | 309, 981, 380, 604, 280 |
| 2 | 309, 981, 190, 302, 140 |
| 3 | 309, 981, 95, 151, 70 |
| 5 | 103, 327, 95, 151, 70 |
| 103, 327, 19, 151, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 103 x 327 x 19 x 151 x 14 = 81169862760
Therefore, the lowest common multiple of 309,981,380,604,280 is 81169862760.
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.
309 x 981 x 380 x 604 x 280 = 19480767062400
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.
309 : 1, 3, 103, 309
981 : 1, 3, 9, 109, 327, 981
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
604 : 1, 2, 4, 151, 302, 604
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,981,380,604,280, is 1.
Now, the common factors can be found like this.
309:3x 103
981:3x 3x 109
380:2x 2x 5x 19
604:2x 2x 151
280:2x 2x 2x 5x 7
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 19480767062400/(1x240)
LCM = 19480767062400/240
LCM = 81169862760
Thus, we can understand that the LCM of 309,981,380,604,280 is 81169862760.
