Given numbers are 822,244,345,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,244,345,161 is 80728620.
Find LCM of 822,244,345,161 with Prime Factorization
2 | 822, 244, 345, 161 |
3 | 411, 122, 345, 161 |
23 | 137, 122, 115, 161 |
137, 122, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 137 x 122 x 5 x 7 = 80728620
Therefore, the lowest common multiple of 822,244,345,161 is 80728620.
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.
822 x 244 x 345 x 161 = 11140549560
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
244 : 1, 2, 4, 61, 122, 244
345 : 1, 3, 5, 15, 23, 69, 115, 345
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,244,345,161, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
244:2x 2x 61
345:3x 5x 23
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 11140549560/(1x138)
LCM = 11140549560/138
LCM = 80728620
Thus, we can understand that the LCM of 822,244,345,161 is 80728620.
