The LCM of 768,994,924,858 is 54582528.
Find LCM of 768,994,924,858 with Prime Factorization
| 2 | 768, 994, 924, 858 |
| 2 | 384, 497, 462, 429 |
| 3 | 192, 497, 231, 429 |
| 7 | 64, 497, 77, 143 |
| 11 | 64, 71, 11, 143 |
| 64, 71, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 64 x 71 x 1 x 13 = 54582528
Therefore, the lowest common multiple of 768,994,924,858 is 54582528.
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.
768 x 994 x 924 x 858 = 605211070464
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
994 : 1, 2, 7, 14, 71, 142, 497, 994
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,994,924,858, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
994:2x 7x 71
924:2x 2x 3x 7x 11
858:2x 3x 11x 13
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 2x 3x 3x 7x 11 = 5544
Therefore, the value for common factors is 5544.
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 = 605211070464/(2x5544)
LCM = 605211070464/11088
LCM = 54582528
Thus, we can understand that the LCM of 768,994,924,858 is 54582528.
