Given numbers are 481,105,903,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,105,903,720 is 104242320.
Find LCM of 481,105,903,720 with Prime Factorization
| 3 | 481, 105, 903, 720 |
| 5 | 481, 35, 301, 240 |
| 7 | 481, 7, 301, 48 |
| 481, 1, 43, 48 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 481 x 1 x 43 x 48 = 104242320
Therefore, the lowest common multiple of 481,105,903,720 is 104242320.
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.
481 x 105 x 903 x 720 = 32836330800
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.
481 : 1, 13, 37, 481
105 : 1, 3, 5, 7, 15, 21, 35, 105
903 : 1, 3, 7, 21, 43, 129, 301, 903
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,105,903,720, is 1.
Now, the common factors can be found like this.
481:13x 37
105:3x 5x 7
903:3x 7x 43
720:2x 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.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 32836330800/(1x315)
LCM = 32836330800/315
LCM = 104242320
Thus, we can understand that the LCM of 481,105,903,720 is 104242320.
