Given numbers are 813,838,793,419
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,838,793,419 is 540266142.
Find LCM of 813,838,793,419 with Prime Factorization
419 | 813, 838, 793, 419 |
813, 2, 793, 1 |
Multiply the prime numbers at the bottom and the left side.
419 x 813 x 2 x 793 x 1 = 540266142
Therefore, the lowest common multiple of 813,838,793,419 is 540266142.
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.
813 x 838 x 793 x 419 = 226371513498
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.
813 : 1, 3, 271, 813
838 : 1, 2, 419, 838
793 : 1, 13, 61, 793
419 : 1, 419
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,838,793,419, is 1.
Now, the common factors can be found like this.
813:3x 271
838:2x 419
793:13x 61
419:419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
419 = 419
Therefore, the value for common factors is 419.
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 = 226371513498/(1x419)
LCM = 226371513498/419
LCM = 540266142
Thus, we can understand that the LCM of 813,838,793,419 is 540266142.
