Given numbers are 403,781,313,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,781,313,793 is 6009388099.
Find LCM of 403,781,313,793 with Prime Factorization
| 13 | 403, 781, 313, 793 |
| 31, 781, 313, 61 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 781 x 313 x 61 = 6009388099
Therefore, the lowest common multiple of 403,781,313,793 is 6009388099.
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.
403 x 781 x 313 x 793 = 78122045287
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.
403 : 1, 13, 31, 403
781 : 1, 11, 71, 781
313 : 1, 313
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,781,313,793, is 1.
Now, the common factors can be found like this.
403:13x 31
781:11x 71
313:313
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 78122045287/(1x13)
LCM = 78122045287/13
LCM = 6009388099
Thus, we can understand that the LCM of 403,781,313,793 is 6009388099.
