Given numbers are 115,911,774,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,911,774,561 is 15163476570.
Find LCM of 115,911,774,561 with Prime Factorization
| 3 | 115, 911, 774, 561 |
| 115, 911, 258, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 115 x 911 x 258 x 187 = 15163476570
Therefore, the lowest common multiple of 115,911,774,561 is 15163476570.
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.
115 x 911 x 774 x 561 = 45490429710
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.
115 : 1, 5, 23, 115
911 : 1, 911
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,911,774,561, is 1.
Now, the common factors can be found like this.
115:5x 23
911:911
774:2x 3x 3x 43
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 45490429710/(1x3)
LCM = 45490429710/3
LCM = 15163476570
Thus, we can understand that the LCM of 115,911,774,561 is 15163476570.
