Given numbers are 284,981,720,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 284,981,720,387 is 239599440.
Find LCM of 284,981,720,387 with Prime Factorization
2 | 284, 981, 720, 387 |
2 | 142, 981, 360, 387 |
3 | 71, 981, 180, 387 |
3 | 71, 327, 60, 129 |
71, 109, 20, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 71 x 109 x 20 x 43 = 239599440
Therefore, the lowest common multiple of 284,981,720,387 is 239599440.
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.
284 x 981 x 720 x 387 = 77630218560
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.
284 : 1, 2, 4, 71, 142, 284
981 : 1, 3, 9, 109, 327, 981
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,981,720,387, is 1.
Now, the common factors can be found like this.
284:2x 2x 71
981:3x 3x 109
720:2x 2x 2x 2x 3x 3x 5
387:3x 3x 43
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 77630218560/(1x324)
LCM = 77630218560/324
LCM = 239599440
Thus, we can understand that the LCM of 284,981,720,387 is 239599440.
