Given numbers are 538,871,155,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,871,155,242 is 8788555490.
Find LCM of 538,871,155,242 with Prime Factorization
| 2 | 538, 871, 155, 242 |
| 269, 871, 155, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 269 x 871 x 155 x 121 = 8788555490
Therefore, the lowest common multiple of 538,871,155,242 is 8788555490.
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 871 x 155 x 242 = 17577110980
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
871 : 1, 13, 67, 871
155 : 1, 5, 31, 155
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,871,155,242, is 1.
Now, the common factors can be found like this.
538:2x 269
871:13x 67
155:5x 31
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 17577110980/(1x2)
LCM = 17577110980/2
LCM = 8788555490
Thus, we can understand that the LCM of 538,871,155,242 is 8788555490.
