Given numbers are 503,355,187,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 503,355,187,781 is 33391655.
Find LCM of 503,355,187,781 with Prime Factorization
| 11 | 503, 355, 187, 781 |
| 71 | 503, 355, 17, 71 |
| 503, 5, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 503 x 5 x 17 x 1 = 33391655
Therefore, the lowest common multiple of 503,355,187,781 is 33391655.
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 355 x 187 x 781 = 26078882555
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
355 : 1, 5, 71, 355
187 : 1, 11, 17, 187
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 503,355,187,781, is 1.
Now, the common factors can be found like this.
503:503
355:5x 71
187:11x 17
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 71 = 781
Therefore, the value for common factors is 781.
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 = 26078882555/(1x781)
LCM = 26078882555/781
LCM = 33391655
Thus, we can understand that the LCM of 503,355,187,781 is 33391655.
