Given numbers are 648,840,467,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 648,840,467,871 is 9225248760.
Find LCM of 648,840,467,871 with Prime Factorization
| 2 | 648, 840, 467, 871 |
| 2 | 324, 420, 467, 871 |
| 2 | 162, 210, 467, 871 |
| 3 | 81, 105, 467, 871 |
| 27, 35, 467, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 27 x 35 x 467 x 871 = 9225248760
Therefore, the lowest common multiple of 648,840,467,871 is 9225248760.
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.
648 x 840 x 467 x 871 = 221405970240
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
467 : 1, 467
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,840,467,871, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
840:2x 2x 2x 3x 5x 7
467:467
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 3 = 24
Therefore, the value for common factors is 24.
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 = 221405970240/(1x24)
LCM = 221405970240/24
LCM = 9225248760
Thus, we can understand that the LCM of 648,840,467,871 is 9225248760.
