Given numbers are 685,470,480,789,250
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,470,480,789,250 is 20321484000.
Find LCM of 685,470,480,789,250 with Prime Factorization
| 2 | 685, 470, 480, 789, 250 |
| 3 | 685, 235, 240, 789, 125 |
| 5 | 685, 235, 80, 263, 125 |
| 137, 47, 16, 263, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 137 x 47 x 16 x 263 x 25 = 20321484000
Therefore, the lowest common multiple of 685,470,480,789,250 is 20321484000.
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.
685 x 470 x 480 x 789 x 250 = 30482226000000
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.
685 : 1, 5, 137, 685
470 : 1, 2, 5, 10, 47, 94, 235, 470
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
789 : 1, 3, 263, 789
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,470,480,789,250, is 1.
Now, the common factors can be found like this.
685:5x 137
470:2x 5x 47
480:2x 2x 2x 2x 2x 3x 5
789:3x 263
250:2x 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.
2x 2x 3x 5x 5x 5 = 1500
Therefore, the value for common factors is 1500.
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 = 30482226000000/(1x1500)
LCM = 30482226000000/1500
LCM = 20321484000
Thus, we can understand that the LCM of 685,470,480,789,250 is 20321484000.
