Given numbers are 398,990,239,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,990,239,195 is 612110070.
Find LCM of 398,990,239,195 with Prime Factorization
2 | 398, 990, 239, 195 |
3 | 199, 495, 239, 195 |
5 | 199, 165, 239, 65 |
199, 33, 239, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 199 x 33 x 239 x 13 = 612110070
Therefore, the lowest common multiple of 398,990,239,195 is 612110070.
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.
398 x 990 x 239 x 195 = 18363302100
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.
398 : 1, 2, 199, 398
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
239 : 1, 239
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,990,239,195, is 1.
Now, the common factors can be found like this.
398:2x 199
990:2x 3x 3x 5x 11
239:239
195:3x 5x 13
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 5 = 30
Therefore, the value for common factors is 30.
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 = 18363302100/(1x30)
LCM = 18363302100/30
LCM = 612110070
Thus, we can understand that the LCM of 398,990,239,195 is 612110070.
