Given numbers are 902,286,836,451,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,286,836,451,669 is 298098372.
Find LCM of 902,286,836,451,669 with Prime Factorization
| 2 | 902, 286, 836, 451, 669 |
| 11 | 451, 143, 418, 451, 669 |
| 41 | 41, 13, 38, 41, 669 |
| 1, 13, 38, 1, 669 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 1 x 13 x 38 x 1 x 669 = 298098372
Therefore, the lowest common multiple of 902,286,836,451,669 is 298098372.
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 286 x 836 x 451 x 669 = 65070105033648
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
451 : 1, 11, 41, 451
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,286,836,451,669, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
286:2x 11x 13
836:2x 2x 11x 19
451:11x 41
669:3x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 11x 11x 41 = 218284
Therefore, the value for common factors is 218284.
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 = 65070105033648/(1x218284)
LCM = 65070105033648/218284
LCM = 298098372
Thus, we can understand that the LCM of 902,286,836,451,669 is 298098372.
