Given numbers are 216,209,539,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 216,209,539,685 is 1515258360.
Find LCM of 216,209,539,685 with Prime Factorization
| 11 | 216, 209, 539, 685 |
| 216, 19, 49, 685 |
Multiply the prime numbers at the bottom and the left side.
11 x 216 x 19 x 49 x 685 = 1515258360
Therefore, the lowest common multiple of 216,209,539,685 is 1515258360.
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.
216 x 209 x 539 x 685 = 16667841960
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
209 : 1, 11, 19, 209
539 : 1, 7, 11, 49, 77, 539
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,209,539,685, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
209:11x 19
539:7x 7x 11
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 16667841960/(1x11)
LCM = 16667841960/11
LCM = 1515258360
Thus, we can understand that the LCM of 216,209,539,685 is 1515258360.
