Given numbers are 345,713,639,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,713,639,197 is 448772895.
Find LCM of 345,713,639,197 with Prime Factorization
| 3 | 345, 713, 639, 197 |
| 23 | 115, 713, 213, 197 |
| 5, 31, 213, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 5 x 31 x 213 x 197 = 448772895
Therefore, the lowest common multiple of 345,713,639,197 is 448772895.
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.
345 x 713 x 639 x 197 = 30965329755
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
713 : 1, 23, 31, 713
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 345,713,639,197, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
713:23x 31
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.
3x 23 = 69
Therefore, the value for common factors is 69.
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 = 30965329755/(1x69)
LCM = 30965329755/69
LCM = 448772895
Thus, we can understand that the LCM of 345,713,639,197 is 448772895.
