Given numbers are 813,254,477,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,254,477,398 is 6533929782.
Find LCM of 813,254,477,398 with Prime Factorization
| 2 | 813, 254, 477, 398 |
| 3 | 813, 127, 477, 199 |
| 271, 127, 159, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 271 x 127 x 159 x 199 = 6533929782
Therefore, the lowest common multiple of 813,254,477,398 is 6533929782.
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 254 x 477 x 398 = 39203578692
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
254 : 1, 2, 127, 254
477 : 1, 3, 9, 53, 159, 477
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,254,477,398, is 1.
Now, the common factors can be found like this.
813:3x 271
254:2x 127
477:3x 3x 53
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 39203578692/(1x6)
LCM = 39203578692/6
LCM = 6533929782
Thus, we can understand that the LCM of 813,254,477,398 is 6533929782.
