Given numbers are 261,762,116,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,762,116,240 is 2651760.
Find LCM of 261,762,116,240 with Prime Factorization
| 2 | 261, 762, 116, 240 |
| 2 | 261, 381, 58, 120 |
| 3 | 261, 381, 29, 60 |
| 29 | 87, 127, 29, 20 |
| 3, 127, 1, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 3 x 127 x 1 x 20 = 2651760
Therefore, the lowest common multiple of 261,762,116,240 is 2651760.
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 762 x 116 x 240 = 5536874880
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
762 : 1, 2, 3, 6, 127, 254, 381, 762
116 : 1, 2, 4, 29, 58, 116
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,762,116,240, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
762:2x 3x 127
116:2x 2x 29
240:2x 2x 2x 2x 3x 5
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 2x 3x 3x 29 = 2088
Therefore, the value for common factors is 2088.
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 = 5536874880/(1x2088)
LCM = 5536874880/2088
LCM = 2651760
Thus, we can understand that the LCM of 261,762,116,240 is 2651760.
