Given numbers are 282,517,357,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,517,357,561 is 369138.
Find LCM of 282,517,357,561 with Prime Factorization
| 3 | 282, 517, 357, 561 |
| 11 | 94, 517, 119, 187 |
| 17 | 94, 47, 119, 17 |
| 47 | 94, 47, 7, 1 |
| 2, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 47 x 2 x 1 x 7 x 1 = 369138
Therefore, the lowest common multiple of 282,517,357,561 is 369138.
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.
282 x 517 x 357 x 561 = 29199184938
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
517 : 1, 11, 47, 517
357 : 1, 3, 7, 17, 21, 51, 119, 357
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 282,517,357,561, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
517:11x 47
357:3x 7x 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.
3x 3x 11x 17x 47 = 79101
Therefore, the value for common factors is 79101.
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 = 29199184938/(1x79101)
LCM = 29199184938/79101
LCM = 369138
Thus, we can understand that the LCM of 282,517,357,561 is 369138.
