Given numbers are 571,492,157,554,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 571,492,157,554,990 is 2015879538420.
Find LCM of 571,492,157,554,990 with Prime Factorization
| 2 | 571, 492, 157, 554, 990 |
| 3 | 571, 246, 157, 277, 495 |
| 571, 82, 157, 277, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 571 x 82 x 157 x 277 x 165 = 2015879538420
Therefore, the lowest common multiple of 571,492,157,554,990 is 2015879538420.
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.
571 x 492 x 157 x 554 x 990 = 24190554461040
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.
571 : 1, 571
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
157 : 1, 157
554 : 1, 2, 277, 554
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 571,492,157,554,990, is 1.
Now, the common factors can be found like this.
571:571
492:2x 2x 3x 41
157:157
554:2x 277
990:2x 3x 3x 5x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 24190554461040/(1x12)
LCM = 24190554461040/12
LCM = 2015879538420
Thus, we can understand that the LCM of 571,492,157,554,990 is 2015879538420.
