The LCM of 738,862,989,144,939 is 787706171568.
Find LCM of 738,862,989,144,939 with Prime Factorization
| 2 | 738, 862, 989, 144, 939 |
| 3 | 369, 431, 989, 72, 939 |
| 3 | 123, 431, 989, 24, 313 |
| 41, 431, 989, 8, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 431 x 989 x 8 x 313 = 787706171568
Therefore, the lowest common multiple of 738,862,989,144,939 is 787706171568.
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.
738 x 862 x 989 x 144 x 939 = 85072266529344
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
862 : 1, 2, 431, 862
989 : 1, 23, 43, 989
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,862,989,144,939, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
862:2x 431
989:23x 43
144:2x 2x 2x 2x 3x 3
939:3x 313
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 3 = 108
Therefore, the value for common factors is 108.
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 = 85072266529344/(1x108)
LCM = 85072266529344/108
LCM = 787706171568
Thus, we can understand that the LCM of 738,862,989,144,939 is 787706171568.
