Given numbers are 866,552,978,297,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,552,978,297,820 is 790685244360.
Find LCM of 866,552,978,297,820 with Prime Factorization
| 2 | 866, 552, 978, 297, 820 |
| 2 | 433, 276, 489, 297, 410 |
| 3 | 433, 138, 489, 297, 205 |
| 433, 46, 163, 99, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 433 x 46 x 163 x 99 x 205 = 790685244360
Therefore, the lowest common multiple of 866,552,978,297,820 is 790685244360.
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.
866 x 552 x 978 x 297 x 820 = 113858675187840
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.
866 : 1, 2, 433, 866
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
978 : 1, 2, 3, 6, 163, 326, 489, 978
297 : 1, 3, 9, 11, 27, 33, 99, 297
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,552,978,297,820, is 1.
Now, the common factors can be found like this.
866:2x 433
552:2x 2x 2x 3x 23
978:2x 3x 163
297:3x 3x 3x 11
820:2x 2x 5x 41
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 113858675187840/(1x144)
LCM = 113858675187840/144
LCM = 790685244360
Thus, we can understand that the LCM of 866,552,978,297,820 is 790685244360.
