Given numbers are 392,788,579,941
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,788,579,941 is 42074646936.
Find LCM of 392,788,579,941 with Prime Factorization
| 2 | 392, 788, 579, 941 |
| 2 | 196, 394, 579, 941 |
| 98, 197, 579, 941 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 98 x 197 x 579 x 941 = 42074646936
Therefore, the lowest common multiple of 392,788,579,941 is 42074646936.
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.
392 x 788 x 579 x 941 = 168298587744
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
788 : 1, 2, 4, 197, 394, 788
579 : 1, 3, 193, 579
941 : 1, 941
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,788,579,941, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
788:2x 2x 197
579:3x 193
941:941
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 168298587744/(1x4)
LCM = 168298587744/4
LCM = 42074646936
Thus, we can understand that the LCM of 392,788,579,941 is 42074646936.
