Given numbers are 679,897,133,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,897,133,989 is 497604471.
Find LCM of 679,897,133,989 with Prime Factorization
7 | 679, 897, 133, 989 |
23 | 97, 897, 19, 989 |
97, 39, 19, 43 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 97 x 39 x 19 x 43 = 497604471
Therefore, the lowest common multiple of 679,897,133,989 is 497604471.
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.
679 x 897 x 133 x 989 = 80114319831
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.
679 : 1, 7, 97, 679
897 : 1, 3, 13, 23, 39, 69, 299, 897
133 : 1, 7, 19, 133
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,897,133,989, is 1.
Now, the common factors can be found like this.
679:7x 97
897:3x 13x 23
133:7x 19
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 80114319831/(1x161)
LCM = 80114319831/161
LCM = 497604471
Thus, we can understand that the LCM of 679,897,133,989 is 497604471.
