Given numbers are 538,706,908,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,706,908,180 is 3879943020.
Find LCM of 538,706,908,180 with Prime Factorization
| 2 | 538, 706, 908, 180 |
| 2 | 269, 353, 454, 90 |
| 269, 353, 227, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 269 x 353 x 227 x 45 = 3879943020
Therefore, the lowest common multiple of 538,706,908,180 is 3879943020.
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 706 x 908 x 180 = 62079088320
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
706 : 1, 2, 353, 706
908 : 1, 2, 4, 227, 454, 908
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,706,908,180, is 2.
Now, the common factors can be found like this.
538:2x 269
706:2x 353
908:2x 2x 227
180:2x 2x 3x 3x 5
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 2 = 8
Therefore, the value for common factors is 8.
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 = 62079088320/(2x8)
LCM = 62079088320/16
LCM = 3879943020
Thus, we can understand that the LCM of 538,706,908,180 is 3879943020.
