Given numbers are 663,815,915,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,815,915,507 is 428493585.
Find LCM of 663,815,915,507 with Prime Factorization
3 | 663, 815, 915, 507 |
5 | 221, 815, 305, 169 |
13 | 221, 163, 61, 169 |
17, 163, 61, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 17 x 163 x 61 x 13 = 428493585
Therefore, the lowest common multiple of 663,815,915,507 is 428493585.
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.
663 x 815 x 915 x 507 = 250668747225
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
815 : 1, 5, 163, 815
915 : 1, 3, 5, 15, 61, 183, 305, 915
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,815,915,507, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
815:5x 163
915:3x 5x 61
507:3x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 13 = 585
Therefore, the value for common factors is 585.
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 = 250668747225/(1x585)
LCM = 250668747225/585
LCM = 428493585
Thus, we can understand that the LCM of 663,815,915,507 is 428493585.
