Given numbers are 961,855,837,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,855,837,991 is 2442780315.
Find LCM of 961,855,837,991 with Prime Factorization
| 3 | 961, 855, 837, 991 |
| 3 | 961, 285, 279, 991 |
| 31 | 961, 95, 93, 991 |
| 31, 95, 3, 991 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 31 x 95 x 3 x 991 = 2442780315
Therefore, the lowest common multiple of 961,855,837,991 is 2442780315.
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.
961 x 855 x 837 x 991 = 681535707885
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.
961 : 1, 31, 961
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
837 : 1, 3, 9, 27, 31, 93, 279, 837
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,855,837,991, is 1.
Now, the common factors can be found like this.
961:31x 31
855:3x 3x 5x 19
837:3x 3x 3x 31
991:991
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 31 = 279
Therefore, the value for common factors is 279.
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 = 681535707885/(1x279)
LCM = 681535707885/279
LCM = 2442780315
Thus, we can understand that the LCM of 961,855,837,991 is 2442780315.
