Given numbers are 268,221,283,459,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,221,283,459,782 is 10408906404.
Find LCM of 268,221,283,459,782 with Prime Factorization
| 2 | 268, 221, 283, 459, 782 |
| 17 | 134, 221, 283, 459, 391 |
| 134, 13, 283, 27, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 134 x 13 x 283 x 27 x 23 = 10408906404
Therefore, the lowest common multiple of 268,221,283,459,782 is 10408906404.
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.
268 x 221 x 283 x 459 x 782 = 6016347901512
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.
268 : 1, 2, 4, 67, 134, 268
221 : 1, 13, 17, 221
283 : 1, 283
459 : 1, 3, 9, 17, 27, 51, 153, 459
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,221,283,459,782, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
221:13x 17
283:283
459:3x 3x 3x 17
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17 = 578
Therefore, the value for common factors is 578.
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 = 6016347901512/(1x578)
LCM = 6016347901512/578
LCM = 10408906404
Thus, we can understand that the LCM of 268,221,283,459,782 is 10408906404.
