Find LCM of 111,979,393,665,655 with Prime Factorization
| 3 | 111, 979, 393, 665, 655 |
| 5 | 37, 979, 131, 665, 655 |
| 131 | 37, 979, 131, 133, 131 |
| 37, 979, 1, 133, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 131 x 37 x 979 x 1 x 133 x 1 = 9466699935
Therefore, the lowest common multiple of 111,979,393,665,655 is 9466699935.
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.
111 x 979 x 393 x 665 x 655 = 18602065372275
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.
111 : 1, 3, 37, 111
979 : 1, 11, 89, 979
393 : 1, 3, 131, 393
665 : 1, 5, 7, 19, 35, 95, 133, 665
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,979,393,665,655, is 1.
Now, the common factors can be found like this.
111:3x 37
979:11x 89
393:3x 131
665:5x 7x 19
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 131 = 1965
Therefore, the value for common factors is 1965.
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 = 18602065372275/(1x1965)
LCM = 18602065372275/1965
LCM = 9466699935
Thus, we can understand that the LCM of 111,979,393,665,655 is 9466699935.
