The LCM of 902,861,966,209 is 8277654.
Find LCM of 902,861,966,209 with Prime Factorization
| 2 | 902, 861, 966, 209 |
| 3 | 451, 861, 483, 209 |
| 7 | 451, 287, 161, 209 |
| 11 | 451, 41, 23, 209 |
| 41 | 41, 41, 23, 19 |
| 1, 1, 23, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 41 x 1 x 1 x 23 x 19 = 8277654
Therefore, the lowest common multiple of 902,861,966,209 is 8277654.
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.
902 x 861 x 966 x 209 = 156795322068
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
861 : 1, 3, 7, 21, 41, 123, 287, 861
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,861,966,209, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
861:3x 7x 41
966:2x 3x 7x 23
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 3x 7x 11x 41 = 18942
Therefore, the value for common factors is 18942.
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 = 156795322068/(1x18942)
LCM = 156795322068/18942
LCM = 8277654
Thus, we can understand that the LCM of 902,861,966,209 is 8277654.
