Given numbers are 326,426,309,643,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,426,309,643,639 is 13796427906.
Find LCM of 326,426,309,643,639 with Prime Factorization
2 | 326, 426, 309, 643, 639 |
3 | 163, 213, 309, 643, 639 |
71 | 163, 71, 103, 643, 213 |
163, 1, 103, 643, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 163 x 1 x 103 x 643 x 3 = 13796427906
Therefore, the lowest common multiple of 326,426,309,643,639 is 13796427906.
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 426 x 309 x 643 x 639 = 17631834863868
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
426 : 1, 2, 3, 6, 71, 142, 213, 426
309 : 1, 3, 103, 309
643 : 1, 643
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 326,426,309,643,639, is 1.
Now, the common factors can be found like this.
326:2x 163
426:2x 3x 71
309:3x 103
643:643
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.
2x 3x 3x 71 = 1278
Therefore, the value for common factors is 1278.
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 = 17631834863868/(1x1278)
LCM = 17631834863868/1278
LCM = 13796427906
Thus, we can understand that the LCM of 326,426,309,643,639 is 13796427906.
