The LCM of 884,243,754,390 is 31147740.
Find LCM of 884,243,754,390 with Prime Factorization
| 2 | 884, 243, 754, 390 |
| 3 | 442, 243, 377, 195 |
| 13 | 442, 81, 377, 65 |
| 34, 81, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 34 x 81 x 29 x 5 = 31147740
Therefore, the lowest common multiple of 884,243,754,390 is 31147740.
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.
884 x 243 x 754 x 390 = 63167616720
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
243 : 1, 3, 9, 27, 81, 243
754 : 1, 2, 13, 26, 29, 58, 377, 754
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,243,754,390, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
243:3x 3x 3x 3x 3
754:2x 13x 29
390:2x 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 2x 3x 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 63167616720/(1x2028)
LCM = 63167616720/2028
LCM = 31147740
Thus, we can understand that the LCM of 884,243,754,390 is 31147740.
