Given numbers are 605,201,286,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,201,286,771 is 812564610.
Find LCM of 605,201,286,771 with Prime Factorization
| 3 | 605, 201, 286, 771 |
| 11 | 605, 67, 286, 257 |
| 55, 67, 26, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 55 x 67 x 26 x 257 = 812564610
Therefore, the lowest common multiple of 605,201,286,771 is 812564610.
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.
605 x 201 x 286 x 771 = 26814632130
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.
605 : 1, 5, 11, 55, 121, 605
201 : 1, 3, 67, 201
286 : 1, 2, 11, 13, 22, 26, 143, 286
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,201,286,771, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
201:3x 67
286:2x 11x 13
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 26814632130/(1x33)
LCM = 26814632130/33
LCM = 812564610
Thus, we can understand that the LCM of 605,201,286,771 is 812564610.
