Given numbers are 383,387,688,339,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 383,387,688,339,305 is 81734988240.
Find LCM of 383,387,688,339,305 with Prime Factorization
| 3 | 383, 387, 688, 339, 305 |
| 43 | 383, 129, 688, 113, 305 |
| 383, 3, 16, 113, 305 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 383 x 3 x 16 x 113 x 305 = 81734988240
Therefore, the lowest common multiple of 383,387,688,339,305 is 81734988240.
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.
383 x 387 x 688 x 339 x 305 = 10543813482960
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.
383 : 1, 383
387 : 1, 3, 9, 43, 129, 387
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
339 : 1, 3, 113, 339
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,387,688,339,305, is 1.
Now, the common factors can be found like this.
383:383
387:3x 3x 43
688:2x 2x 2x 2x 43
339:3x 113
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 10543813482960/(1x129)
LCM = 10543813482960/129
LCM = 81734988240
Thus, we can understand that the LCM of 383,387,688,339,305 is 81734988240.
