Given numbers are 981,860,637,847,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,860,637,847,847 is 65026781820.
Find LCM of 981,860,637,847,847 with Prime Factorization
7 | 981, 860, 637, 847, 847 |
11 | 981, 860, 91, 121, 121 |
11 | 981, 860, 91, 11, 11 |
981, 860, 91, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 11 x 981 x 860 x 91 x 1 x 1 = 65026781820
Therefore, the lowest common multiple of 981,860,637,847,847 is 65026781820.
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.
981 x 860 x 637 x 847 x 847 = 385543789410780
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.
981 : 1, 3, 9, 109, 327, 981
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
637 : 1, 7, 13, 49, 91, 637
847 : 1, 7, 11, 77, 121, 847
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,860,637,847,847, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
860:2x 2x 5x 43
637:7x 7x 13
847:7x 11x 11
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 11x 11 = 5929
Therefore, the value for common factors is 5929.
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 = 385543789410780/(1x5929)
LCM = 385543789410780/5929
LCM = 65026781820
Thus, we can understand that the LCM of 981,860,637,847,847 is 65026781820.
