Given numbers are 347,556,682,161,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,556,682,161,394 is 2086655467204.
Find LCM of 347,556,682,161,394 with Prime Factorization
| 2 | 347, 556, 682, 161, 394 |
| 347, 278, 341, 161, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 347 x 278 x 341 x 161 x 197 = 2086655467204
Therefore, the lowest common multiple of 347,556,682,161,394 is 2086655467204.
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.
347 x 556 x 682 x 161 x 394 = 8346621868816
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.
347 : 1, 347
556 : 1, 2, 4, 139, 278, 556
682 : 1, 2, 11, 22, 31, 62, 341, 682
161 : 1, 7, 23, 161
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,556,682,161,394, is 1.
Now, the common factors can be found like this.
347:347
556:2x 2x 139
682:2x 11x 31
161:7x 23
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 8346621868816/(1x4)
LCM = 8346621868816/4
LCM = 2086655467204
Thus, we can understand that the LCM of 347,556,682,161,394 is 2086655467204.
