Given numbers are 823,249,161,639,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,249,161,639,197 is 1384429637367.
Find LCM of 823,249,161,639,197 with Prime Factorization
| 3 | 823, 249, 161, 639, 197 |
| 823, 83, 161, 213, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 823 x 83 x 161 x 213 x 197 = 1384429637367
Therefore, the lowest common multiple of 823,249,161,639,197 is 1384429637367.
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.
823 x 249 x 161 x 639 x 197 = 4153288912101
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.
823 : 1, 823
249 : 1, 3, 83, 249
161 : 1, 7, 23, 161
639 : 1, 3, 9, 71, 213, 639
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,249,161,639,197, is 1.
Now, the common factors can be found like this.
823:823
249:3x 83
161:7x 23
639:3x 3x 71
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 4153288912101/(1x3)
LCM = 4153288912101/3
LCM = 1384429637367
Thus, we can understand that the LCM of 823,249,161,639,197 is 1384429637367.
