Given numbers are 450,685,989,285,625
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,685,989,285,625 is 28961628750.
Find LCM of 450,685,989,285,625 with Prime Factorization
| 3 | 450, 685, 989, 285, 625 |
| 5 | 150, 685, 989, 95, 625 |
| 5 | 30, 137, 989, 19, 125 |
| 6, 137, 989, 19, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 6 x 137 x 989 x 19 x 25 = 28961628750
Therefore, the lowest common multiple of 450,685,989,285,625 is 28961628750.
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.
450 x 685 x 989 x 285 x 625 = 54303053906250
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
685 : 1, 5, 137, 685
989 : 1, 23, 43, 989
285 : 1, 3, 5, 15, 19, 57, 95, 285
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 450,685,989,285,625, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
685:5x 137
989:23x 43
285:3x 5x 19
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.
3x 5x 5x 5x 5 = 1875
Therefore, the value for common factors is 1875.
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 = 54303053906250/(1x1875)
LCM = 54303053906250/1875
LCM = 28961628750
Thus, we can understand that the LCM of 450,685,989,285,625 is 28961628750.
