Given numbers are 843,961,256,779,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,961,256,779,123 is 161557969152.
Find LCM of 843,961,256,779,123 with Prime Factorization
| 3 | 843, 961, 256, 779, 123 |
| 41 | 281, 961, 256, 779, 41 |
| 281, 961, 256, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 281 x 961 x 256 x 19 x 1 = 161557969152
Therefore, the lowest common multiple of 843,961,256,779,123 is 161557969152.
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.
843 x 961 x 256 x 779 x 123 = 19871630205696
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.
843 : 1, 3, 281, 843
961 : 1, 31, 961
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
779 : 1, 19, 41, 779
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,961,256,779,123, is 1.
Now, the common factors can be found like this.
843:3x 281
961:31x 31
256:2x 2x 2x 2x 2x 2x 2x 2
779:19x 41
123:3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 19871630205696/(1x123)
LCM = 19871630205696/123
LCM = 161557969152
Thus, we can understand that the LCM of 843,961,256,779,123 is 161557969152.
