The LCM of 918,766,446,918 is 78405462.
Find LCM of 918,766,446,918 with Prime Factorization
| 2 | 918, 766, 446, 918 |
| 3 | 459, 383, 223, 459 |
| 3 | 153, 383, 223, 153 |
| 3 | 51, 383, 223, 51 |
| 17 | 17, 383, 223, 17 |
| 1, 383, 223, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 1 x 383 x 223 x 1 = 78405462
Therefore, the lowest common multiple of 918,766,446,918 is 78405462.
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.
918 x 766 x 446 x 918 = 287904856464
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
766 : 1, 2, 383, 766
446 : 1, 2, 223, 446
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,766,446,918, is 2.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
766:2x 383
446:2x 223
918:2x 3x 3x 3x 17
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 3x 3x 3x 17 = 1836
Therefore, the value for common factors is 1836.
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 = 287904856464/(2x1836)
LCM = 287904856464/3672
LCM = 78405462
Thus, we can understand that the LCM of 918,766,446,918 is 78405462.
