Given numbers are 756,218,388,435,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,218,388,435,102 is 19703208420.
Find LCM of 756,218,388,435,102 with Prime Factorization
| 2 | 756, 218, 388, 435, 102 |
| 2 | 378, 109, 194, 435, 51 |
| 3 | 189, 109, 97, 435, 51 |
| 63, 109, 97, 145, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 63 x 109 x 97 x 145 x 17 = 19703208420
Therefore, the lowest common multiple of 756,218,388,435,102 is 19703208420.
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.
756 x 218 x 388 x 435 x 102 = 2837262012480
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
218 : 1, 2, 109, 218
388 : 1, 2, 4, 97, 194, 388
435 : 1, 3, 5, 15, 29, 87, 145, 435
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,218,388,435,102, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
218:2x 109
388:2x 2x 97
435:3x 5x 29
102:2x 3x 17
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 2837262012480/(1x144)
LCM = 2837262012480/144
LCM = 19703208420
Thus, we can understand that the LCM of 756,218,388,435,102 is 19703208420.
