The LCM of 625,390,975,905 is 8823750.
Find LCM of 625,390,975,905 with Prime Factorization
| 3 | 625, 390, 975, 905 |
| 5 | 625, 130, 325, 905 |
| 5 | 125, 26, 65, 181 |
| 13 | 25, 26, 13, 181 |
| 25, 2, 1, 181 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 13 x 25 x 2 x 1 x 181 = 8823750
Therefore, the lowest common multiple of 625,390,975,905 is 8823750.
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.
625 x 390 x 975 x 905 = 215078906250
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.
625 : 1, 5, 25, 125, 625
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
905 : 1, 5, 181, 905
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,390,975,905, is 5.
Now, the common factors can be found like this.
625:5x 5x 5x 5
390:2x 3x 5x 13
975:3x 5x 5x 13
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5x 13 = 4875
Therefore, the value for common factors is 4875.
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 = 215078906250/(5x4875)
LCM = 215078906250/24375
LCM = 8823750
Thus, we can understand that the LCM of 625,390,975,905 is 8823750.
