Given numbers are 985,975,394,625
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,975,394,625 is 9603750.
Find LCM of 985,975,394,625 with Prime Factorization
| 5 | 985, 975, 394, 625 |
| 5 | 197, 195, 394, 125 |
| 197 | 197, 39, 394, 25 |
| 1, 39, 2, 25 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 197 x 1 x 39 x 2 x 25 = 9603750
Therefore, the lowest common multiple of 985,975,394,625 is 9603750.
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.
985 x 975 x 394 x 625 = 236492343750
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.
985 : 1, 5, 197, 985
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
394 : 1, 2, 197, 394
625 : 1, 5, 25, 125, 625
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,975,394,625, is 1.
Now, the common factors can be found like this.
985:5x 197
975:3x 5x 5x 13
394:2x 197
625:5x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5x 197 = 24625
Therefore, the value for common factors is 24625.
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 = 236492343750/(1x24625)
LCM = 236492343750/24625
LCM = 9603750
Thus, we can understand that the LCM of 985,975,394,625 is 9603750.
