Given numbers are 107,720,646,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,720,646,696 is 721633680.
Find LCM of 107,720,646,696 with Prime Factorization
| 2 | 107, 720, 646, 696 |
| 2 | 107, 360, 323, 348 |
| 2 | 107, 180, 323, 174 |
| 3 | 107, 90, 323, 87 |
| 107, 30, 323, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 107 x 30 x 323 x 29 = 721633680
Therefore, the lowest common multiple of 107,720,646,696 is 721633680.
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.
107 x 720 x 646 x 696 = 34638416640
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.
107 : 1, 107
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,720,646,696, is 1.
Now, the common factors can be found like this.
107:107
720:2x 2x 2x 2x 3x 3x 5
646:2x 17x 19
696:2x 2x 2x 3x 29
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 3 = 48
Therefore, the value for common factors is 48.
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 = 34638416640/(1x48)
LCM = 34638416640/48
LCM = 721633680
Thus, we can understand that the LCM of 107,720,646,696 is 721633680.
