Find LCM of 399,810,117,939,774 with Prime Factorization
2 | 399, 810, 117, 939, 774 |
3 | 399, 405, 117, 939, 387 |
3 | 133, 135, 39, 313, 129 |
133, 45, 13, 313, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 133 x 45 x 13 x 313 x 43 = 18849194910
Therefore, the lowest common multiple of 399,810,117,939,774 is 18849194910.
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.
399 x 810 x 117 x 939 x 774 = 27482126178780
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
117 : 1, 3, 9, 13, 39, 117
939 : 1, 3, 313, 939
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,810,117,939,774, is 3.
Now, the common factors can be found like this.
399:3x 7x 19
810:2x 3x 3x 3x 3x 5
117:3x 3x 13
939:3x 313
774:2x 3x 3x 43
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 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 27482126178780/(3x486)
LCM = 27482126178780/1458
LCM = 18849194910
Thus, we can understand that the LCM of 399,810,117,939,774 is 18849194910.
