Find LCM of 105,546,988,839,771 with Prime Factorization
| 2 | 105, 546, 988, 839, 771 |
| 3 | 105, 273, 494, 839, 771 |
| 7 | 35, 91, 494, 839, 257 |
| 13 | 5, 13, 494, 839, 257 |
| 5, 1, 38, 839, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 5 x 1 x 38 x 839 x 257 = 22368730020
Therefore, the lowest common multiple of 105,546,988,839,771 is 22368730020.
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.
105 x 546 x 988 x 839 x 771 = 36639979772760
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
839 : 1, 839
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,546,988,839,771, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
546:2x 3x 7x 13
988:2x 2x 13x 19
839:839
771:3x 257
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 3x 7x 13 = 1638
Therefore, the value for common factors is 1638.
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 = 36639979772760/(1x1638)
LCM = 36639979772760/1638
LCM = 22368730020
Thus, we can understand that the LCM of 105,546,988,839,771 is 22368730020.
