Find LCM of 128,751,182,720,845 with Prime Factorization
| 2 | 128, 751, 182, 720, 845 |
| 2 | 64, 751, 91, 360, 845 |
| 2 | 32, 751, 91, 180, 845 |
| 2 | 16, 751, 91, 90, 845 |
| 5 | 8, 751, 91, 45, 845 |
| 13 | 8, 751, 91, 9, 169 |
| 8, 751, 7, 9, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 13 x 8 x 751 x 7 x 9 x 13 = 5117374080
Therefore, the lowest common multiple of 128,751,182,720,845 is 5117374080.
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.
128 x 751 x 182 x 720 x 845 = 10644138086400
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
751 : 1, 751
182 : 1, 2, 7, 13, 14, 26, 91, 182
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
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,751,182,720,845, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
751:751
182:2x 7x 13
720:2x 2x 2x 2x 3x 3x 5
845:5x 13x 13
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 2x 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 10644138086400/(1x2080)
LCM = 10644138086400/2080
LCM = 5117374080
Thus, we can understand that the LCM of 128,751,182,720,845 is 5117374080.
