Given numbers are 418,571,538,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,571,538,154 is 449430674.
Find LCM of 418,571,538,154 with Prime Factorization
2 | 418, 571, 538, 154 |
11 | 209, 571, 269, 77 |
19, 571, 269, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 571 x 269 x 7 = 449430674
Therefore, the lowest common multiple of 418,571,538,154 is 449430674.
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.
418 x 571 x 538 x 154 = 19774949656
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
571 : 1, 571
538 : 1, 2, 269, 538
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,571,538,154, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
571:571
538:2x 269
154:2x 7x 11
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 11 = 44
Therefore, the value for common factors is 44.
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 = 19774949656/(1x44)
LCM = 19774949656/44
LCM = 449430674
Thus, we can understand that the LCM of 418,571,538,154 is 449430674.
