The LCM of 891,563,792,345 is 461502360.
Find LCM of 891,563,792,345 with Prime Factorization
| 3 | 891, 563, 792, 345 |
| 3 | 297, 563, 264, 115 |
| 11 | 99, 563, 88, 115 |
| 9, 563, 8, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 9 x 563 x 8 x 115 = 461502360
Therefore, the lowest common multiple of 891,563,792,345 is 461502360.
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.
891 x 563 x 792 x 345 = 137066200920
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
563 : 1, 563
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
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,563,792,345, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
563:563
792:2x 2x 2x 3x 3x 11
345:3x 5x 23
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 11 = 297
Therefore, the value for common factors is 297.
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 = 137066200920/(1x297)
LCM = 137066200920/297
LCM = 461502360
Thus, we can understand that the LCM of 891,563,792,345 is 461502360.
