Find LCM of 770,285,244,845,455 with Prime Factorization
| 2 | 770, 285, 244, 845, 455 |
| 5 | 385, 285, 122, 845, 455 |
| 7 | 77, 57, 122, 169, 91 |
| 13 | 11, 57, 122, 169, 13 |
| 11, 57, 122, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 11 x 57 x 122 x 1 x 13 = 904924020
Therefore, the lowest common multiple of 770,285,244,845,455 is 904924020.
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.
770 x 285 x 244 x 845 x 455 = 20587021455000
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
285 : 1, 3, 5, 15, 19, 57, 95, 285
244 : 1, 2, 4, 61, 122, 244
845 : 1, 5, 13, 65, 169, 845
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,285,244,845,455, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
285:3x 5x 19
244:2x 2x 61
845:5x 13x 13
455:5x 7x 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 5x 5x 5x 7x 13 = 22750
Therefore, the value for common factors is 22750.
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 = 20587021455000/(1x22750)
LCM = 20587021455000/22750
LCM = 904924020
Thus, we can understand that the LCM of 770,285,244,845,455 is 904924020.
