Find LCM of 609,858,671,847,691 with Prime Factorization
| 3 | 609, 858, 671, 847, 691 |
| 7 | 203, 286, 671, 847, 691 |
| 11 | 29, 286, 671, 121, 691 |
| 29, 26, 61, 11, 691 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 29 x 26 x 61 x 11 x 691 = 80757691014
Therefore, the lowest common multiple of 609,858,671,847,691 is 80757691014.
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.
609 x 858 x 671 x 847 x 691 = 205205292866574
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
671 : 1, 11, 61, 671
847 : 1, 7, 11, 77, 121, 847
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,858,671,847,691, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
858:2x 3x 11x 13
671:11x 61
847:7x 11x 11
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11x 11 = 2541
Therefore, the value for common factors is 2541.
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 = 205205292866574/(1x2541)
LCM = 205205292866574/2541
LCM = 80757691014
Thus, we can understand that the LCM of 609,858,671,847,691 is 80757691014.
