Given numbers are 668,241,781,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,241,781,442 is 27786689788.
Find LCM of 668,241,781,442 with Prime Factorization
2 | 668, 241, 781, 442 |
334, 241, 781, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 334 x 241 x 781 x 221 = 27786689788
Therefore, the lowest common multiple of 668,241,781,442 is 27786689788.
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.
668 x 241 x 781 x 442 = 55573379576
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.
668 : 1, 2, 4, 167, 334, 668
241 : 1, 241
781 : 1, 11, 71, 781
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,241,781,442, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
241:241
781:11x 71
442:2x 13x 17
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 = 55573379576/(1x2)
LCM = 55573379576/2
LCM = 27786689788
Thus, we can understand that the LCM of 668,241,781,442 is 27786689788.
