Given numbers are 985,903,920,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,903,920,360 is 490979160.
Find LCM of 985,903,920,360 with Prime Factorization
| 2 | 985, 903, 920, 360 |
| 2 | 985, 903, 460, 180 |
| 2 | 985, 903, 230, 90 |
| 3 | 985, 903, 115, 45 |
| 5 | 985, 301, 115, 15 |
| 197, 301, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 197 x 301 x 23 x 3 = 490979160
Therefore, the lowest common multiple of 985,903,920,360 is 490979160.
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 903 x 920 x 360 = 294587496000
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
903 : 1, 3, 7, 21, 43, 129, 301, 903
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,903,920,360, is 1.
Now, the common factors can be found like this.
985:5x 197
903:3x 7x 43
920:2x 2x 2x 5x 23
360:2x 2x 2x 3x 3x 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 2x 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 294587496000/(1x600)
LCM = 294587496000/600
LCM = 490979160
Thus, we can understand that the LCM of 985,903,920,360 is 490979160.
