Find LCM of 638,965,990,760,927 with Prime Factorization
2 | 638, 965, 990, 760, 927 |
3 | 319, 965, 495, 380, 927 |
3 | 319, 965, 165, 380, 309 |
5 | 319, 965, 55, 380, 103 |
11 | 319, 193, 11, 76, 103 |
29, 193, 1, 76, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 29 x 193 x 1 x 76 x 103 = 43375182840
Therefore, the lowest common multiple of 638,965,990,760,927 is 43375182840.
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.
638 x 965 x 990 x 760 x 927 = 429414310116000
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
965 : 1, 5, 193, 965
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
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
927 : 1, 3, 9, 103, 309, 927
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,965,990,760,927, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
965:5x 193
990:2x 3x 3x 5x 11
760:2x 2x 2x 5x 19
927:3x 3x 103
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 3x 3x 5x 5x 11 = 9900
Therefore, the value for common factors is 9900.
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 = 429414310116000/(1x9900)
LCM = 429414310116000/9900
LCM = 43375182840
Thus, we can understand that the LCM of 638,965,990,760,927 is 43375182840.
