Given numbers are 908,433,990,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 908,433,990,989 is 192475402020.
Find LCM of 908,433,990,989 with Prime Factorization
2 | 908, 433, 990, 989 |
454, 433, 495, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 454 x 433 x 495 x 989 = 192475402020
Therefore, the lowest common multiple of 908,433,990,989 is 192475402020.
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.
908 x 433 x 990 x 989 = 384950804040
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.
908 : 1, 2, 4, 227, 454, 908
433 : 1, 433
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
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,433,990,989, is 1.
Now, the common factors can be found like this.
908:2x 2x 227
433:433
990:2x 3x 3x 5x 11
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 384950804040/(1x2)
LCM = 384950804040/2
LCM = 192475402020
Thus, we can understand that the LCM of 908,433,990,989 is 192475402020.
