Given numbers are 161,828,158,779,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,828,158,779,678 is 40306154868.
Find LCM of 161,828,158,779,678 with Prime Factorization
| 2 | 161, 828, 158, 779, 678 |
| 3 | 161, 414, 79, 779, 339 |
| 23 | 161, 138, 79, 779, 113 |
| 7, 6, 79, 779, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 7 x 6 x 79 x 779 x 113 = 40306154868
Therefore, the lowest common multiple of 161,828,158,779,678 is 40306154868.
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.
161 x 828 x 158 x 779 x 678 = 11124498743568
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.
161 : 1, 7, 23, 161
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
158 : 1, 2, 79, 158
779 : 1, 19, 41, 779
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,828,158,779,678, is 1.
Now, the common factors can be found like this.
161:7x 23
828:2x 2x 3x 3x 23
158:2x 79
779:19x 41
678:2x 3x 113
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 11124498743568/(1x276)
LCM = 11124498743568/276
LCM = 40306154868
Thus, we can understand that the LCM of 161,828,158,779,678 is 40306154868.
