Given numbers are 725,173,285,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,173,285,245 is 350312025.
Find LCM of 725,173,285,245 with Prime Factorization
| 5 | 725, 173, 285, 245 |
| 145, 173, 57, 49 |
Multiply the prime numbers at the bottom and the left side.
5 x 145 x 173 x 57 x 49 = 350312025
Therefore, the lowest common multiple of 725,173,285,245 is 350312025.
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.
725 x 173 x 285 x 245 = 8757800625
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.
725 : 1, 5, 25, 29, 145, 725
173 : 1, 173
285 : 1, 3, 5, 15, 19, 57, 95, 285
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,173,285,245, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
173:173
285:3x 5x 19
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 8757800625/(1x25)
LCM = 8757800625/25
LCM = 350312025
Thus, we can understand that the LCM of 725,173,285,245 is 350312025.
