Given numbers are 771,909,213,805,881
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,909,213,805,881 is 11763245044215.
Find LCM of 771,909,213,805,881 with Prime Factorization
| 3 | 771, 909, 213, 805, 881 |
| 257, 303, 71, 805, 881 |
Multiply the prime numbers at the bottom and the left side.
3 x 257 x 303 x 71 x 805 x 881 = 11763245044215
Therefore, the lowest common multiple of 771,909,213,805,881 is 11763245044215.
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.
771 x 909 x 213 x 805 x 881 = 105869205397935
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.
771 : 1, 3, 257, 771
909 : 1, 3, 9, 101, 303, 909
213 : 1, 3, 71, 213
805 : 1, 5, 7, 23, 35, 115, 161, 805
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,909,213,805,881, is 1.
Now, the common factors can be found like this.
771:3x 257
909:3x 3x 101
213:3x 71
805:5x 7x 23
881:881
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 105869205397935/(1x9)
LCM = 105869205397935/9
LCM = 11763245044215
Thus, we can understand that the LCM of 771,909,213,805,881 is 11763245044215.
