Given numbers are 388,970,225,339
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,970,225,339 is 9864900.
Find LCM of 388,970,225,339 with Prime Factorization
| 2 | 388, 970, 225, 339 |
| 3 | 194, 485, 225, 339 |
| 5 | 194, 485, 75, 113 |
| 97 | 194, 97, 15, 113 |
| 2, 1, 15, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 97 x 2 x 1 x 15 x 113 = 9864900
Therefore, the lowest common multiple of 388,970,225,339 is 9864900.
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.
388 x 970 x 225 x 339 = 28706859000
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.
388 : 1, 2, 4, 97, 194, 388
970 : 1, 2, 5, 10, 97, 194, 485, 970
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
339 : 1, 3, 113, 339
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,970,225,339, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
970:2x 5x 97
225:3x 3x 5x 5
339:3x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 97 = 2910
Therefore, the value for common factors is 2910.
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 = 28706859000/(1x2910)
LCM = 28706859000/2910
LCM = 9864900
Thus, we can understand that the LCM of 388,970,225,339 is 9864900.
