Given numbers are 815,658,847,652
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,658,847,652 is 129777340.
Find LCM of 815,658,847,652 with Prime Factorization
2 | 815, 658, 847, 652 |
7 | 815, 329, 847, 326 |
163 | 815, 47, 121, 326 |
5, 47, 121, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 163 x 5 x 47 x 121 x 2 = 129777340
Therefore, the lowest common multiple of 815,658,847,652 is 129777340.
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.
815 x 658 x 847 x 652 = 296151889880
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.
815 : 1, 5, 163, 815
658 : 1, 2, 7, 14, 47, 94, 329, 658
847 : 1, 7, 11, 77, 121, 847
652 : 1, 2, 4, 163, 326, 652
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,658,847,652, is 1.
Now, the common factors can be found like this.
815:5x 163
658:2x 7x 47
847:7x 11x 11
652:2x 2x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 163 = 2282
Therefore, the value for common factors is 2282.
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 = 296151889880/(1x2282)
LCM = 296151889880/2282
LCM = 129777340
Thus, we can understand that the LCM of 815,658,847,652 is 129777340.
