The LCM of 874,782,691,691 is 10266878.
Find LCM of 874,782,691,691 with Prime Factorization
| 2 | 874, 782, 691, 691 |
| 23 | 437, 391, 691, 691 |
| 691 | 19, 17, 691, 691 |
| 19, 17, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 691 x 19 x 17 x 1 x 1 = 10266878
Therefore, the lowest common multiple of 874,782,691,691 is 10266878.
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.
874 x 782 x 691 x 691 = 326342984108
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
782 : 1, 2, 17, 23, 34, 46, 391, 782
691 : 1, 691
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,782,691,691, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
782:2x 17x 23
691:691
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.
2x 23x 691 = 31786
Therefore, the value for common factors is 31786.
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 = 326342984108/(1x31786)
LCM = 326342984108/31786
LCM = 10266878
Thus, we can understand that the LCM of 874,782,691,691 is 10266878.
