Given numbers are 718,687,670,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,687,670,792 is 21812222520.
Find LCM of 718,687,670,792 with Prime Factorization
| 2 | 718, 687, 670, 792 |
| 3 | 359, 687, 335, 396 |
| 359, 229, 335, 132 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 359 x 229 x 335 x 132 = 21812222520
Therefore, the lowest common multiple of 718,687,670,792 is 21812222520.
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.
718 x 687 x 670 x 792 = 261746670240
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.
718 : 1, 2, 359, 718
687 : 1, 3, 229, 687
670 : 1, 2, 5, 10, 67, 134, 335, 670
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,687,670,792, is 1.
Now, the common factors can be found like this.
718:2x 359
687:3x 229
670:2x 5x 67
792:2x 2x 2x 3x 3x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 261746670240/(1x12)
LCM = 261746670240/12
LCM = 21812222520
Thus, we can understand that the LCM of 718,687,670,792 is 21812222520.
