Given numbers are 777,109,981,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,109,981,315 is 1270395.
Find LCM of 777,109,981,315 with Prime Factorization
| 3 | 777, 109, 981, 315 |
| 3 | 259, 109, 327, 105 |
| 7 | 259, 109, 109, 35 |
| 109 | 37, 109, 109, 5 |
| 37, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 109 x 37 x 1 x 1 x 5 = 1270395
Therefore, the lowest common multiple of 777,109,981,315 is 1270395.
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.
777 x 109 x 981 x 315 = 26171407395
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
109 : 1, 109
981 : 1, 3, 9, 109, 327, 981
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,109,981,315, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
109:109
981:3x 3x 109
315:3x 3x 5x 7
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 7x 109 = 20601
Therefore, the value for common factors is 20601.
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 = 26171407395/(1x20601)
LCM = 26171407395/20601
LCM = 1270395
Thus, we can understand that the LCM of 777,109,981,315 is 1270395.
