Given numbers are 781,587,939,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,587,939,313 is 430481733.
Find LCM of 781,587,939,313 with Prime Factorization
| 313 | 781, 587, 939, 313 |
| 781, 587, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
313 x 781 x 587 x 3 x 1 = 430481733
Therefore, the lowest common multiple of 781,587,939,313 is 430481733.
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.
781 x 587 x 939 x 313 = 134740782429
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.
781 : 1, 11, 71, 781
587 : 1, 587
939 : 1, 3, 313, 939
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,587,939,313, is 1.
Now, the common factors can be found like this.
781:11x 71
587:587
939:3x 313
313:313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
313 = 313
Therefore, the value for common factors is 313.
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 = 134740782429/(1x313)
LCM = 134740782429/313
LCM = 430481733
Thus, we can understand that the LCM of 781,587,939,313 is 430481733.
