Given numbers are 489,111,781,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,111,781,144 is 678270384.
Find LCM of 489,111,781,144 with Prime Factorization
3 | 489, 111, 781, 144 |
163, 37, 781, 48 |
Multiply the prime numbers at the bottom and the left side.
3 x 163 x 37 x 781 x 48 = 678270384
Therefore, the lowest common multiple of 489,111,781,144 is 678270384.
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.
489 x 111 x 781 x 144 = 6104433456
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.
489 : 1, 3, 163, 489
111 : 1, 3, 37, 111
781 : 1, 11, 71, 781
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,111,781,144, is 1.
Now, the common factors can be found like this.
489:3x 163
111:3x 37
781:11x 71
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 6104433456/(1x9)
LCM = 6104433456/9
LCM = 678270384
Thus, we can understand that the LCM of 489,111,781,144 is 678270384.
