Given numbers are 524,831,558,786,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 524,831,558,786,639 is 2875236732.
Find LCM of 524,831,558,786,639 with Prime Factorization
| 2 | 524, 831, 558, 786, 639 |
| 3 | 262, 831, 279, 393, 639 |
| 3 | 262, 277, 93, 131, 213 |
| 131 | 262, 277, 31, 131, 71 |
| 2, 277, 31, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 131 x 2 x 277 x 31 x 1 x 71 = 2875236732
Therefore, the lowest common multiple of 524,831,558,786,639 is 2875236732.
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.
524 x 831 x 558 x 786 x 639 = 122036547853008
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.
524 : 1, 2, 4, 131, 262, 524
831 : 1, 3, 277, 831
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
786 : 1, 2, 3, 6, 131, 262, 393, 786
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,831,558,786,639, is 1.
Now, the common factors can be found like this.
524:2x 2x 131
831:3x 277
558:2x 3x 3x 31
786:2x 3x 131
639:3x 3x 71
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 3x 3x 131 = 42444
Therefore, the value for common factors is 42444.
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 = 122036547853008/(1x42444)
LCM = 122036547853008/42444
LCM = 2875236732
Thus, we can understand that the LCM of 524,831,558,786,639 is 2875236732.
