Find LCM of 642,924,990,766,547 with Prime Factorization
2 | 642, 924, 990, 766, 547 |
3 | 321, 462, 495, 383, 547 |
11 | 107, 154, 165, 383, 547 |
107, 14, 15, 383, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 107 x 14 x 15 x 383 x 547 = 310694173020
Therefore, the lowest common multiple of 642,924,990,766,547 is 310694173020.
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.
642 x 924 x 990 x 766 x 547 = 246069785031840
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
766 : 1, 2, 383, 766
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,924,990,766,547, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
924:2x 2x 3x 7x 11
990:2x 3x 3x 5x 11
766:2x 383
547:547
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 11 = 792
Therefore, the value for common factors is 792.
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 = 246069785031840/(1x792)
LCM = 246069785031840/792
LCM = 310694173020
Thus, we can understand that the LCM of 642,924,990,766,547 is 310694173020.
