Given numbers are 538,278,942,819,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,278,942,819,387 is 413474837958.
Find LCM of 538,278,942,819,387 with Prime Factorization
| 2 | 538, 278, 942, 819, 387 |
| 3 | 269, 139, 471, 819, 387 |
| 3 | 269, 139, 157, 273, 129 |
| 269, 139, 157, 91, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 269 x 139 x 157 x 91 x 43 = 413474837958
Therefore, the lowest common multiple of 538,278,942,819,387 is 413474837958.
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.
538 x 278 x 942 x 819 x 387 = 44655282499464
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.
538 : 1, 2, 269, 538
278 : 1, 2, 139, 278
942 : 1, 2, 3, 6, 157, 314, 471, 942
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,278,942,819,387, is 1.
Now, the common factors can be found like this.
538:2x 269
278:2x 139
942:2x 3x 157
819:3x 3x 7x 13
387:3x 3x 43
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 3 = 108
Therefore, the value for common factors is 108.
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 = 44655282499464/(1x108)
LCM = 44655282499464/108
LCM = 413474837958
Thus, we can understand that the LCM of 538,278,942,819,387 is 413474837958.
