Given numbers are 247,124,437,636,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,124,437,636,218 is 12208718964.
Find LCM of 247,124,437,636,218 with Prime Factorization
| 2 | 247, 124, 437, 636, 218 |
| 2 | 247, 62, 437, 318, 109 |
| 19 | 247, 31, 437, 159, 109 |
| 13, 31, 23, 159, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 13 x 31 x 23 x 159 x 109 = 12208718964
Therefore, the lowest common multiple of 247,124,437,636,218 is 12208718964.
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.
247 x 124 x 437 x 636 x 218 = 1855725282528
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.
247 : 1, 13, 19, 247
124 : 1, 2, 4, 31, 62, 124
437 : 1, 19, 23, 437
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,124,437,636,218, is 1.
Now, the common factors can be found like this.
247:13x 19
124:2x 2x 31
437:19x 23
636:2x 2x 3x 53
218:2x 109
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 19 = 152
Therefore, the value for common factors is 152.
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 = 1855725282528/(1x152)
LCM = 1855725282528/152
LCM = 12208718964
Thus, we can understand that the LCM of 247,124,437,636,218 is 12208718964.
