Find LCM of 868,603,871,408,561 with Prime Factorization
| 2 | 868, 603, 871, 408, 561 |
| 2 | 434, 603, 871, 204, 561 |
| 3 | 217, 603, 871, 102, 561 |
| 17 | 217, 201, 871, 34, 187 |
| 67 | 217, 201, 871, 2, 11 |
| 217, 3, 13, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 67 x 217 x 3 x 13 x 2 x 11 = 2544790248
Therefore, the lowest common multiple of 868,603,871,408,561 is 2544790248.
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.
868 x 603 x 871 x 408 x 561 = 104346579328992
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
603 : 1, 3, 9, 67, 201, 603
871 : 1, 13, 67, 871
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,603,871,408,561, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
603:3x 3x 67
871:13x 67
408:2x 2x 2x 3x 17
561:3x 11x 17
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 3x 3x 17x 67 = 41004
Therefore, the value for common factors is 41004.
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 = 104346579328992/(1x41004)
LCM = 104346579328992/41004
LCM = 2544790248
Thus, we can understand that the LCM of 868,603,871,408,561 is 2544790248.
