Given numbers are 398,921,190,274,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,921,190,274,135 is 42936771330.
Find LCM of 398,921,190,274,135 with Prime Factorization
| 2 | 398, 921, 190, 274, 135 |
| 3 | 199, 921, 95, 137, 135 |
| 5 | 199, 307, 95, 137, 45 |
| 199, 307, 19, 137, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 199 x 307 x 19 x 137 x 9 = 42936771330
Therefore, the lowest common multiple of 398,921,190,274,135 is 42936771330.
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.
398 x 921 x 190 x 274 x 135 = 2576206279800
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.
398 : 1, 2, 199, 398
921 : 1, 3, 307, 921
190 : 1, 2, 5, 10, 19, 38, 95, 190
274 : 1, 2, 137, 274
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,921,190,274,135, is 1.
Now, the common factors can be found like this.
398:2x 199
921:3x 307
190:2x 5x 19
274:2x 137
135:3x 3x 3x 5
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 5 = 60
Therefore, the value for common factors is 60.
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 = 2576206279800/(1x60)
LCM = 2576206279800/60
LCM = 42936771330
Thus, we can understand that the LCM of 398,921,190,274,135 is 42936771330.
