Given numbers are 538,247,100,687,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,247,100,687,394 is 899232917700.
Find LCM of 538,247,100,687,394 with Prime Factorization
| 2 | 538, 247, 100, 687, 394 |
| 269, 247, 50, 687, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 269 x 247 x 50 x 687 x 197 = 899232917700
Therefore, the lowest common multiple of 538,247,100,687,394 is 899232917700.
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 247 x 100 x 687 x 394 = 3596931670800
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
247 : 1, 13, 19, 247
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
687 : 1, 3, 229, 687
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,247,100,687,394, is 1.
Now, the common factors can be found like this.
538:2x 269
247:13x 19
100:2x 2x 5x 5
687:3x 229
394:2x 197
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 = 3596931670800/(1x4)
LCM = 3596931670800/4
LCM = 899232917700
Thus, we can understand that the LCM of 538,247,100,687,394 is 899232917700.
