Given numbers are 871,649,558,718,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,649,558,718,640 is 36236102348160.
Find LCM of 871,649,558,718,640 with Prime Factorization
2 | 871, 649, 558, 718, 640 |
871, 649, 279, 359, 320 |
Multiply the prime numbers at the bottom and the left side.
2 x 871 x 649 x 279 x 359 x 320 = 36236102348160
Therefore, the lowest common multiple of 871,649,558,718,640 is 36236102348160.
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.
871 x 649 x 558 x 718 x 640 = 144944409392640
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.
871 : 1, 13, 67, 871
649 : 1, 11, 59, 649
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
718 : 1, 2, 359, 718
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,649,558,718,640, is 1.
Now, the common factors can be found like this.
871:13x 67
649:11x 59
558:2x 3x 3x 31
718:2x 359
640:2x 2x 2x 2x 2x 2x 2x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 144944409392640/(1x4)
LCM = 144944409392640/4
LCM = 36236102348160
Thus, we can understand that the LCM of 871,649,558,718,640 is 36236102348160.
