Given numbers are 247,665,903,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,665,903,247 is 1115205.
Find LCM of 247,665,903,247 with Prime Factorization
7 | 247, 665, 903, 247 |
13 | 247, 95, 129, 247 |
19 | 19, 95, 129, 19 |
1, 5, 129, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 19 x 1 x 5 x 129 x 1 = 1115205
Therefore, the lowest common multiple of 247,665,903,247 is 1115205.
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 665 x 903 x 247 = 36635599455
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
665 : 1, 5, 7, 19, 35, 95, 133, 665
903 : 1, 3, 7, 21, 43, 129, 301, 903
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,665,903,247, is 1.
Now, the common factors can be found like this.
247:13x 19
665:5x 7x 19
903:3x 7x 43
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 19x 19 = 32851
Therefore, the value for common factors is 32851.
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 = 36635599455/(1x32851)
LCM = 36635599455/32851
LCM = 1115205
Thus, we can understand that the LCM of 247,665,903,247 is 1115205.
