Given numbers are 389,428,631,631,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,428,631,631,783 is 82259201916.
Find LCM of 389,428,631,631,783 with Prime Factorization
631 | 389, 428, 631, 631, 783 |
389, 428, 1, 1, 783 |
Multiply the prime numbers at the bottom and the left side.
631 x 389 x 428 x 1 x 1 x 783 = 82259201916
Therefore, the lowest common multiple of 389,428,631,631,783 is 82259201916.
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.
389 x 428 x 631 x 631 x 783 = 51905556408996
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.
389 : 1, 389
428 : 1, 2, 4, 107, 214, 428
631 : 1, 631
631 : 1, 631
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,428,631,631,783, is 1.
Now, the common factors can be found like this.
389:389
428:2x 2x 107
631:631
631:631
783:3x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
631 = 631
Therefore, the value for common factors is 631.
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 = 51905556408996/(1x631)
LCM = 51905556408996/631
LCM = 82259201916
Thus, we can understand that the LCM of 389,428,631,631,783 is 82259201916.
