Given numbers are 126,918,439,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,918,439,720 is 112840560.
Find LCM of 126,918,439,720 with Prime Factorization
| 2 | 126, 918, 439, 720 |
| 3 | 63, 459, 439, 360 |
| 3 | 21, 153, 439, 120 |
| 7, 51, 439, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 51 x 439 x 40 = 112840560
Therefore, the lowest common multiple of 126,918,439,720 is 112840560.
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.
126 x 918 x 439 x 720 = 36560341440
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
439 : 1, 439
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,918,439,720, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
918:2x 3x 3x 3x 17
439:439
720:2x 2x 2x 2x 3x 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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 36560341440/(1x324)
LCM = 36560341440/324
LCM = 112840560
Thus, we can understand that the LCM of 126,918,439,720 is 112840560.
