Given numbers are 394,923,611,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,923,611,578 is 4939620946.
Find LCM of 394,923,611,578 with Prime Factorization
| 2 | 394, 923, 611, 578 |
| 13 | 197, 923, 611, 289 |
| 197, 71, 47, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 197 x 71 x 47 x 289 = 4939620946
Therefore, the lowest common multiple of 394,923,611,578 is 4939620946.
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.
394 x 923 x 611 x 578 = 128430144596
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.
394 : 1, 2, 197, 394
923 : 1, 13, 71, 923
611 : 1, 13, 47, 611
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,923,611,578, is 1.
Now, the common factors can be found like this.
394:2x 197
923:13x 71
611:13x 47
578:2x 17x 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 13 = 26
Therefore, the value for common factors is 26.
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 = 128430144596/(1x26)
LCM = 128430144596/26
LCM = 4939620946
Thus, we can understand that the LCM of 394,923,611,578 is 4939620946.
