Given numbers are 717,231,847,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,231,847,560 is 48583920.
Find LCM of 717,231,847,560 with Prime Factorization
| 3 | 717, 231, 847, 560 |
| 7 | 239, 77, 847, 560 |
| 11 | 239, 11, 121, 80 |
| 239, 1, 11, 80 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 239 x 1 x 11 x 80 = 48583920
Therefore, the lowest common multiple of 717,231,847,560 is 48583920.
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.
717 x 231 x 847 x 560 = 78560198640
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.
717 : 1, 3, 239, 717
231 : 1, 3, 7, 11, 21, 33, 77, 231
847 : 1, 7, 11, 77, 121, 847
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,231,847,560, is 1.
Now, the common factors can be found like this.
717:3x 239
231:3x 7x 11
847:7x 11x 11
560:2x 2x 2x 2x 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 7x 7x 11 = 1617
Therefore, the value for common factors is 1617.
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 = 78560198640/(1x1617)
LCM = 78560198640/1617
LCM = 48583920
Thus, we can understand that the LCM of 717,231,847,560 is 48583920.
