The LCM of 494,978,741,856 is 103390248.
Find LCM of 494,978,741,856 with Prime Factorization
| 2 | 494, 978, 741, 856 |
| 3 | 247, 489, 741, 428 |
| 13 | 247, 163, 247, 428 |
| 19 | 19, 163, 19, 428 |
| 1, 163, 1, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 1 x 163 x 1 x 428 = 103390248
Therefore, the lowest common multiple of 494,978,741,856 is 103390248.
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.
494 x 978 x 741 x 856 = 306448695072
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
978 : 1, 2, 3, 6, 163, 326, 489, 978
741 : 1, 3, 13, 19, 39, 57, 247, 741
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,978,741,856, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
978:2x 3x 163
741:3x 13x 19
856:2x 2x 2x 107
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 13x 19 = 2964
Therefore, the value for common factors is 2964.
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 = 306448695072/(1x2964)
LCM = 306448695072/2964
LCM = 103390248
Thus, we can understand that the LCM of 494,978,741,856 is 103390248.
