Given numbers are 643,282,428,224,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,282,428,224,486 is 176013873504.
Find LCM of 643,282,428,224,486 with Prime Factorization
| 2 | 643, 282, 428, 224, 486 |
| 2 | 643, 141, 214, 112, 243 |
| 3 | 643, 141, 107, 56, 243 |
| 643, 47, 107, 56, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 643 x 47 x 107 x 56 x 81 = 176013873504
Therefore, the lowest common multiple of 643,282,428,224,486 is 176013873504.
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.
643 x 282 x 428 x 224 x 486 = 8448665928192
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.
643 : 1, 643
282 : 1, 2, 3, 6, 47, 94, 141, 282
428 : 1, 2, 4, 107, 214, 428
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,282,428,224,486, is 1.
Now, the common factors can be found like this.
643:643
282:2x 3x 47
428:2x 2x 107
224:2x 2x 2x 2x 2x 7
486:2x 3x 3x 3x 3x 3
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 3 = 48
Therefore, the value for common factors is 48.
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 = 8448665928192/(1x48)
LCM = 8448665928192/48
LCM = 176013873504
Thus, we can understand that the LCM of 643,282,428,224,486 is 176013873504.
