Given numbers are 115,191,484,978,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,191,484,978,774 is 670617895860.
Find LCM of 115,191,484,978,774 with Prime Factorization
| 2 | 115, 191, 484, 978, 774 |
| 3 | 115, 191, 242, 489, 387 |
| 115, 191, 242, 163, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 115 x 191 x 242 x 163 x 129 = 670617895860
Therefore, the lowest common multiple of 115,191,484,978,774 is 670617895860.
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 191 x 484 x 978 x 774 = 8047414750320
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
191 : 1, 191
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
978 : 1, 2, 3, 6, 163, 326, 489, 978
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,191,484,978,774, is 1.
Now, the common factors can be found like this.
115:5x 23
191:191
484:2x 2x 11x 11
978:2x 3x 163
774:2x 3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 8047414750320/(1x12)
LCM = 8047414750320/12
LCM = 670617895860
Thus, we can understand that the LCM of 115,191,484,978,774 is 670617895860.
