Given numbers are 656,252,872,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,252,872,217 is 139647312.
Find LCM of 656,252,872,217 with Prime Factorization
2 | 656, 252, 872, 217 |
2 | 328, 126, 436, 217 |
2 | 164, 63, 218, 217 |
7 | 82, 63, 109, 217 |
82, 9, 109, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 82 x 9 x 109 x 31 = 139647312
Therefore, the lowest common multiple of 656,252,872,217 is 139647312.
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.
656 x 252 x 872 x 217 = 31280997888
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
872 : 1, 2, 4, 8, 109, 218, 436, 872
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,252,872,217, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
252:2x 2x 3x 3x 7
872:2x 2x 2x 109
217:7x 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 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 31280997888/(1x224)
LCM = 31280997888/224
LCM = 139647312
Thus, we can understand that the LCM of 656,252,872,217 is 139647312.
