Given numbers are 261,959,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,959,685 is 1251495.
Find LCM of 261,959,685 with Prime Factorization
| 137 | 261, 959, 685 |
| 261, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
137 x 261 x 7 x 5 = 1251495
Therefore, the lowest common multiple of 261,959,685 is 1251495.
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.
261 x 959 x 685 = 171454815
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.
261 : 1, 3, 9, 29, 87, 261
959 : 1, 7, 137, 959
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,959,685, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
959:7x 137
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
137 = 137
Therefore, the value for common factors is 137.
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 = 171454815/(1x137)
LCM = 171454815/137
LCM = 1251495
Thus, we can understand that the LCM of 261,959,685 is 1251495.
