The LCM of 503,990,638,342 is 274381470.
Find LCM of 503,990,638,342 with Prime Factorization
| 2 | 503, 990, 638, 342 |
| 3 | 503, 495, 319, 171 |
| 3 | 503, 165, 319, 57 |
| 11 | 503, 55, 319, 19 |
| 503, 5, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 503 x 5 x 29 x 19 = 274381470
Therefore, the lowest common multiple of 503,990,638,342 is 274381470.
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.
503 x 990 x 638 x 342 = 108655062120
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.
503 : 1, 503
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 503,990,638,342, is 1.
Now, the common factors can be found like this.
503:503
990:2x 3x 3x 5x 11
638:2x 11x 29
342:2x 3x 3x 19
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 11 = 396
Therefore, the value for common factors is 396.
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 = 108655062120/(1x396)
LCM = 108655062120/396
LCM = 274381470
Thus, we can understand that the LCM of 503,990,638,342 is 274381470.
