Find LCM of 605,121,973,898,380 with Prime Factorization
| 2 | 605, 121, 973, 898, 380 |
| 5 | 605, 121, 973, 449, 190 |
| 11 | 121, 121, 973, 449, 38 |
| 11 | 11, 11, 973, 449, 38 |
| 1, 1, 973, 449, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 1 x 1 x 973 x 449 x 38 = 20087604460
Therefore, the lowest common multiple of 605,121,973,898,380 is 20087604460.
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.
605 x 121 x 973 x 898 x 380 = 24306001396600
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.
605 : 1, 5, 11, 55, 121, 605
121 : 1, 11, 121
973 : 1, 7, 139, 973
898 : 1, 2, 449, 898
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,121,973,898,380, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
121:11x 11
973:7x 139
898:2x 449
380:2x 2x 5x 19
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 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 24306001396600/(1x1210)
LCM = 24306001396600/1210
LCM = 20087604460
Thus, we can understand that the LCM of 605,121,973,898,380 is 20087604460.
