Given numbers are 656,911,285,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,911,285,638 is 54332258640.
Find LCM of 656,911,285,638 with Prime Factorization
2 | 656, 911, 285, 638 |
328, 911, 285, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 328 x 911 x 285 x 319 = 54332258640
Therefore, the lowest common multiple of 656,911,285,638 is 54332258640.
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.
656 x 911 x 285 x 638 = 108664517280
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
911 : 1, 911
285 : 1, 3, 5, 15, 19, 57, 95, 285
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,911,285,638, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
911:911
285:3x 5x 19
638:2x 11x 29
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 = 108664517280/(1x2)
LCM = 108664517280/2
LCM = 54332258640
Thus, we can understand that the LCM of 656,911,285,638 is 54332258640.
