The LCM of 632,790,400,871 is 27523600.
Find LCM of 632,790,400,871 with Prime Factorization
| 2 | 632, 790, 400, 871 |
| 2 | 316, 395, 200, 871 |
| 2 | 158, 395, 100, 871 |
| 5 | 79, 395, 50, 871 |
| 79 | 79, 79, 10, 871 |
| 1, 1, 10, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 79 x 1 x 1 x 10 x 871 = 27523600
Therefore, the lowest common multiple of 632,790,400,871 is 27523600.
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.
632 x 790 x 400 x 871 = 173949152000
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
790 : 1, 2, 5, 10, 79, 158, 395, 790
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,790,400,871, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
790:2x 5x 79
400:2x 2x 2x 2x 5x 5
871:13x 67
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 2x 2x 5x 79 = 6320
Therefore, the value for common factors is 6320.
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 = 173949152000/(1x6320)
LCM = 173949152000/6320
LCM = 27523600
Thus, we can understand that the LCM of 632,790,400,871 is 27523600.
