Given numbers are 674,993,618,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,993,618,993 is 68936046.
Find LCM of 674,993,618,993 with Prime Factorization
| 2 | 674, 993, 618, 993 |
| 3 | 337, 993, 309, 993 |
| 331 | 337, 331, 103, 331 |
| 337, 1, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 337 x 1 x 103 x 1 = 68936046
Therefore, the lowest common multiple of 674,993,618,993 is 68936046.
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.
674 x 993 x 618 x 993 = 410720962068
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.
674 : 1, 2, 337, 674
993 : 1, 3, 331, 993
618 : 1, 2, 3, 6, 103, 206, 309, 618
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,993,618,993, is 1.
Now, the common factors can be found like this.
674:2x 337
993:3x 331
618:2x 3x 103
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 331 = 5958
Therefore, the value for common factors is 5958.
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 = 410720962068/(1x5958)
LCM = 410720962068/5958
LCM = 68936046
Thus, we can understand that the LCM of 674,993,618,993 is 68936046.
