Find LCM of 903,427,183,644,989 with Prime Factorization
3 | 903, 427, 183, 644, 989 |
7 | 301, 427, 61, 644, 989 |
23 | 43, 61, 61, 92, 989 |
43 | 43, 61, 61, 4, 43 |
61 | 1, 61, 61, 4, 1 |
1, 1, 1, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 23 x 43 x 61 x 1 x 1 x 1 x 4 x 1 = 5067636
Therefore, the lowest common multiple of 903,427,183,644,989 is 5067636.
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.
903 x 427 x 183 x 644 x 989 = 44941635599868
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
427 : 1, 7, 61, 427
183 : 1, 3, 61, 183
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,427,183,644,989, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
427:7x 61
183:3x 61
644:2x 2x 7x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 23x 43x 61 = 8868363
Therefore, the value for common factors is 8868363.
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 = 44941635599868/(1x8868363)
LCM = 44941635599868/8868363
LCM = 5067636
Thus, we can understand that the LCM of 903,427,183,644,989 is 5067636.
