Given numbers are 634,616,788,616,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,616,788,616,686 is 1884960616.
Find LCM of 634,616,788,616,686 with Prime Factorization
| 2 | 634, 616, 788, 616, 686 |
| 2 | 317, 308, 394, 308, 343 |
| 2 | 317, 154, 197, 154, 343 |
| 7 | 317, 77, 197, 77, 343 |
| 11 | 317, 11, 197, 11, 49 |
| 317, 1, 197, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 317 x 1 x 197 x 1 x 49 = 1884960616
Therefore, the lowest common multiple of 634,616,788,616,686 is 1884960616.
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.
634 x 616 x 788 x 616 x 686 = 130047202819072
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.
634 : 1, 2, 317, 634
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
788 : 1, 2, 4, 197, 394, 788
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,616,788,616,686, is 2.
Now, the common factors can be found like this.
634:2x 317
616:2x 2x 2x 7x 11
788:2x 2x 197
616:2x 2x 2x 7x 11
686:2x 7x 7x 7
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 2x 7x 7x 11 = 34496
Therefore, the value for common factors is 34496.
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 = 130047202819072/(2x34496)
LCM = 130047202819072/68992
LCM = 1884960616
Thus, we can understand that the LCM of 634,616,788,616,686 is 1884960616.
