Find LCM of 819,485,321,985,315 with Prime Factorization
3 | 819, 485, 321, 985, 315 |
3 | 273, 485, 107, 985, 105 |
5 | 91, 485, 107, 985, 35 |
7 | 91, 97, 107, 197, 7 |
13, 97, 107, 197, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 13 x 97 x 107 x 197 x 1 = 8372894985
Therefore, the lowest common multiple of 819,485,321,985,315 is 8372894985.
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.
819 x 485 x 321 x 985 x 315 = 39561928804125
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
485 : 1, 5, 97, 485
321 : 1, 3, 107, 321
985 : 1, 5, 197, 985
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,485,321,985,315, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
485:5x 97
321:3x 107
985:5x 197
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5x 7 = 4725
Therefore, the value for common factors is 4725.
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 = 39561928804125/(1x4725)
LCM = 39561928804125/4725
LCM = 8372894985
Thus, we can understand that the LCM of 819,485,321,985,315 is 8372894985.
