Given numbers are 218,986,527,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,986,527,868 is 46643716.
Find LCM of 218,986,527,868 with Prime Factorization
| 2 | 218, 986, 527, 868 |
| 17 | 109, 493, 527, 434 |
| 31 | 109, 29, 31, 434 |
| 109, 29, 1, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 31 x 109 x 29 x 1 x 14 = 46643716
Therefore, the lowest common multiple of 218,986,527,868 is 46643716.
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.
218 x 986 x 527 x 868 = 98324953328
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.
218 : 1, 2, 109, 218
986 : 1, 2, 17, 29, 34, 58, 493, 986
527 : 1, 17, 31, 527
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,986,527,868, is 1.
Now, the common factors can be found like this.
218:2x 109
986:2x 17x 29
527:17x 31
868:2x 2x 7x 31
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 17x 31 = 2108
Therefore, the value for common factors is 2108.
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 = 98324953328/(1x2108)
LCM = 98324953328/2108
LCM = 46643716
Thus, we can understand that the LCM of 218,986,527,868 is 46643716.
