Given numbers are 326,638,343,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,638,343,639 is 22793092938.
Find LCM of 326,638,343,639 with Prime Factorization
| 2 | 326, 638, 343, 639 |
| 163, 319, 343, 639 |
Multiply the prime numbers at the bottom and the left side.
2 x 163 x 319 x 343 x 639 = 22793092938
Therefore, the lowest common multiple of 326,638,343,639 is 22793092938.
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.
326 x 638 x 343 x 639 = 45586185876
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.
326 : 1, 2, 163, 326
638 : 1, 2, 11, 22, 29, 58, 319, 638
343 : 1, 7, 49, 343
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,638,343,639, is 1.
Now, the common factors can be found like this.
326:2x 163
638:2x 11x 29
343:7x 7x 7
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 45586185876/(1x2)
LCM = 45586185876/2
LCM = 22793092938
Thus, we can understand that the LCM of 326,638,343,639 is 22793092938.
