Given numbers are 494,534,713,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 494,534,713,989 is 4043860782.
Find LCM of 494,534,713,989 with Prime Factorization
| 2 | 494, 534, 713, 989 |
| 23 | 247, 267, 713, 989 |
| 247, 267, 31, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 247 x 267 x 31 x 43 = 4043860782
Therefore, the lowest common multiple of 494,534,713,989 is 4043860782.
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.
494 x 534 x 713 x 989 = 186017595972
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
534 : 1, 2, 3, 6, 89, 178, 267, 534
713 : 1, 23, 31, 713
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,534,713,989, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
534:2x 3x 89
713:23x 31
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23 = 46
Therefore, the value for common factors is 46.
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 = 186017595972/(1x46)
LCM = 186017595972/46
LCM = 4043860782
Thus, we can understand that the LCM of 494,534,713,989 is 4043860782.
