Given numbers are 554,642,762,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,642,762,818 is 9237231462.
Find LCM of 554,642,762,818 with Prime Factorization
| 2 | 554, 642, 762, 818 |
| 3 | 277, 321, 381, 409 |
| 277, 107, 127, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 277 x 107 x 127 x 409 = 9237231462
Therefore, the lowest common multiple of 554,642,762,818 is 9237231462.
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.
554 x 642 x 762 x 818 = 221693555088
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.
554 : 1, 2, 277, 554
642 : 1, 2, 3, 6, 107, 214, 321, 642
762 : 1, 2, 3, 6, 127, 254, 381, 762
818 : 1, 2, 409, 818
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,642,762,818, is 2.
Now, the common factors can be found like this.
554:2x 277
642:2x 3x 107
762:2x 3x 127
818:2x 409
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 3 = 12
Therefore, the value for common factors is 12.
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 = 221693555088/(2x12)
LCM = 221693555088/24
LCM = 9237231462
Thus, we can understand that the LCM of 554,642,762,818 is 9237231462.
