The LCM of 836,849,561,665 is 422309580.
Find LCM of 836,849,561,665 with Prime Factorization
| 3 | 836, 849, 561, 665 |
| 11 | 836, 283, 187, 665 |
| 19 | 76, 283, 17, 665 |
| 4, 283, 17, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 4 x 283 x 17 x 35 = 422309580
Therefore, the lowest common multiple of 836,849,561,665 is 422309580.
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.
836 x 849 x 561 x 665 = 264788106660
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
849 : 1, 3, 283, 849
561 : 1, 3, 11, 17, 33, 51, 187, 561
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,849,561,665, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
849:3x 283
561:3x 11x 17
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19 = 627
Therefore, the value for common factors is 627.
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 = 264788106660/(1x627)
LCM = 264788106660/627
LCM = 422309580
Thus, we can understand that the LCM of 836,849,561,665 is 422309580.
