Given numbers are 797,480,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,480,105 is 2677920.
Find LCM of 797,480,105 with Prime Factorization
| 3 | 797, 480, 105 |
| 5 | 797, 160, 35 |
| 797, 32, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 797 x 32 x 7 = 2677920
Therefore, the lowest common multiple of 797,480,105 is 2677920.
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.
797 x 480 x 105 = 40168800
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.
797 : 1, 797
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
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,480,105, is 1.
Now, the common factors can be found like this.
797:797
480:2x 2x 2x 2x 2x 3x 5
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 40168800/(1x15)
LCM = 40168800/15
LCM = 2677920
Thus, we can understand that the LCM of 797,480,105 is 2677920.
