Given numbers are 858,989,818,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,989,818,611 is 16311907326.
Find LCM of 858,989,818,611 with Prime Factorization
| 2 | 858, 989, 818, 611 |
| 13 | 429, 989, 409, 611 |
| 33, 989, 409, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 33 x 989 x 409 x 47 = 16311907326
Therefore, the lowest common multiple of 858,989,818,611 is 16311907326.
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.
858 x 989 x 818 x 611 = 424109590476
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
989 : 1, 23, 43, 989
818 : 1, 2, 409, 818
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,989,818,611, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
989:23x 43
818:2x 409
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 424109590476/(1x26)
LCM = 424109590476/26
LCM = 16311907326
Thus, we can understand that the LCM of 858,989,818,611 is 16311907326.
