Find LCM of 605,605,838,788,664 with Prime Factorization
| 2 | 605, 605, 838, 788, 664 |
| 2 | 605, 605, 419, 394, 332 |
| 5 | 605, 605, 419, 197, 166 |
| 11 | 121, 121, 419, 197, 166 |
| 11 | 11, 11, 419, 197, 166 |
| 1, 1, 419, 197, 166 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 11 x 1 x 1 x 419 x 197 x 166 = 33159173960
Therefore, the lowest common multiple of 605,605,838,788,664 is 33159173960.
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 605 x 838 x 788 x 664 = 160490401966400
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
605 : 1, 5, 11, 55, 121, 605
838 : 1, 2, 419, 838
788 : 1, 2, 4, 197, 394, 788
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,605,838,788,664, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
605:5x 11x 11
838:2x 419
788:2x 2x 197
664:2x 2x 2x 83
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 5x 11x 11 = 4840
Therefore, the value for common factors is 4840.
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 = 160490401966400/(1x4840)
LCM = 160490401966400/4840
LCM = 33159173960
Thus, we can understand that the LCM of 605,605,838,788,664 is 33159173960.
