Given numbers are 438,808,727,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,808,727,168 is 900508728.
Find LCM of 438,808,727,168 with Prime Factorization
2 | 438, 808, 727, 168 |
2 | 219, 404, 727, 84 |
2 | 219, 202, 727, 42 |
3 | 219, 101, 727, 21 |
73, 101, 727, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 73 x 101 x 727 x 7 = 900508728
Therefore, the lowest common multiple of 438,808,727,168 is 900508728.
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.
438 x 808 x 727 x 168 = 43224418944
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
808 : 1, 2, 4, 8, 101, 202, 404, 808
727 : 1, 727
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,808,727,168, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
808:2x 2x 2x 101
727:727
168:2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 43224418944/(1x48)
LCM = 43224418944/48
LCM = 900508728
Thus, we can understand that the LCM of 438,808,727,168 is 900508728.
