Given numbers are 720,600,447,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,600,447,938 is 251571600.
Find LCM of 720,600,447,938 with Prime Factorization
| 2 | 720, 600, 447, 938 |
| 2 | 360, 300, 447, 469 |
| 2 | 180, 150, 447, 469 |
| 3 | 90, 75, 447, 469 |
| 5 | 30, 25, 149, 469 |
| 6, 5, 149, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 6 x 5 x 149 x 469 = 251571600
Therefore, the lowest common multiple of 720,600,447,938 is 251571600.
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.
720 x 600 x 447 x 938 = 181131552000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
447 : 1, 3, 149, 447
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,600,447,938, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
600:2x 2x 2x 3x 5x 5
447:3x 149
938:2x 7x 67
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 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 181131552000/(1x720)
LCM = 181131552000/720
LCM = 251571600
Thus, we can understand that the LCM of 720,600,447,938 is 251571600.
