Find LCM of 891,858,618,829,661 with Prime Factorization
| 2 | 891, 858, 618, 829, 661 |
| 3 | 891, 429, 309, 829, 661 |
| 11 | 297, 143, 103, 829, 661 |
| 27, 13, 103, 829, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 27 x 13 x 103 x 829 x 661 = 1307507734962
Therefore, the lowest common multiple of 891,858,618,829,661 is 1307507734962.
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.
891 x 858 x 618 x 829 x 661 = 258886531522476
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
618 : 1, 2, 3, 6, 103, 206, 309, 618
829 : 1, 829
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,858,618,829,661, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
858:2x 3x 11x 13
618:2x 3x 103
829:829
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 258886531522476/(1x198)
LCM = 258886531522476/198
LCM = 1307507734962
Thus, we can understand that the LCM of 891,858,618,829,661 is 1307507734962.
