Given numbers are 287,297,779,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,297,779,121 is 17814951.
Find LCM of 287,297,779,121 with Prime Factorization
| 11 | 287, 297, 779, 121 |
| 41 | 287, 27, 779, 11 |
| 7, 27, 19, 11 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 7 x 27 x 19 x 11 = 17814951
Therefore, the lowest common multiple of 287,297,779,121 is 17814951.
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.
287 x 297 x 779 x 121 = 8034542901
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.
287 : 1, 7, 41, 287
297 : 1, 3, 9, 11, 27, 33, 99, 297
779 : 1, 19, 41, 779
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,297,779,121, is 1.
Now, the common factors can be found like this.
287:7x 41
297:3x 3x 3x 11
779:19x 41
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 41 = 451
Therefore, the value for common factors is 451.
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 = 8034542901/(1x451)
LCM = 8034542901/451
LCM = 17814951
Thus, we can understand that the LCM of 287,297,779,121 is 17814951.
