Given numbers are 115,648,759,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,648,759,171 is 15574680.
Find LCM of 115,648,759,171 with Prime Factorization
| 3 | 115, 648, 759, 171 |
| 3 | 115, 216, 253, 57 |
| 23 | 115, 72, 253, 19 |
| 5, 72, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 5 x 72 x 11 x 19 = 15574680
Therefore, the lowest common multiple of 115,648,759,171 is 15574680.
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 648 x 759 x 171 = 9671876280
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
759 : 1, 3, 11, 23, 33, 69, 253, 759
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,648,759,171, is 1.
Now, the common factors can be found like this.
115:5x 23
648:2x 2x 2x 3x 3x 3x 3
759:3x 11x 23
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 23 = 621
Therefore, the value for common factors is 621.
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 = 9671876280/(1x621)
LCM = 9671876280/621
LCM = 15574680
Thus, we can understand that the LCM of 115,648,759,171 is 15574680.
