Given numbers are 211,605,770,220,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,605,770,220,209 is 67912460.
Find LCM of 211,605,770,220,209 with Prime Factorization
| 2 | 211, 605, 770, 220, 209 |
| 5 | 211, 605, 385, 110, 209 |
| 11 | 211, 121, 77, 22, 209 |
| 211, 11, 7, 2, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 211 x 11 x 7 x 2 x 19 = 67912460
Therefore, the lowest common multiple of 211,605,770,220,209 is 67912460.
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.
211 x 605 x 770 x 220 x 209 = 4519574213000
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.
211 : 1, 211
605 : 1, 5, 11, 55, 121, 605
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,605,770,220,209, is 1.
Now, the common factors can be found like this.
211:211
605:5x 11x 11
770:2x 5x 7x 11
220:2x 2x 5x 11
209:11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 11x 11 = 66550
Therefore, the value for common factors is 66550.
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 = 4519574213000/(1x66550)
LCM = 4519574213000/66550
LCM = 67912460
Thus, we can understand that the LCM of 211,605,770,220,209 is 67912460.
