Given numbers are 687,625,793,275
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,625,793,275 is 3745438125.
Find LCM of 687,625,793,275 with Prime Factorization
| 5 | 687, 625, 793, 275 |
| 5 | 687, 125, 793, 55 |
| 687, 25, 793, 11 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 687 x 25 x 793 x 11 = 3745438125
Therefore, the lowest common multiple of 687,625,793,275 is 3745438125.
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.
687 x 625 x 793 x 275 = 93635953125
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.
687 : 1, 3, 229, 687
625 : 1, 5, 25, 125, 625
793 : 1, 13, 61, 793
275 : 1, 5, 11, 25, 55, 275
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,625,793,275, is 1.
Now, the common factors can be found like this.
687:3x 229
625:5x 5x 5x 5
793:13x 61
275:5x 5x 11
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 = 93635953125/(1x25)
LCM = 93635953125/25
LCM = 3745438125
Thus, we can understand that the LCM of 687,625,793,275 is 3745438125.
