Given numbers are 329,315,978,681,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 329,315,978,681,245 is 7669197270.
Find LCM of 329,315,978,681,245 with Prime Factorization
| 3 | 329, 315, 978, 681, 245 |
| 5 | 329, 105, 326, 227, 245 |
| 7 | 329, 21, 326, 227, 49 |
| 47, 3, 326, 227, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 47 x 3 x 326 x 227 x 7 = 7669197270
Therefore, the lowest common multiple of 329,315,978,681,245 is 7669197270.
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.
329 x 315 x 978 x 681 x 245 = 16910579980350
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.
329 : 1, 7, 47, 329
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
978 : 1, 2, 3, 6, 163, 326, 489, 978
681 : 1, 3, 227, 681
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,315,978,681,245, is 1.
Now, the common factors can be found like this.
329:7x 47
315:3x 3x 5x 7
978:2x 3x 163
681:3x 227
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7x 7 = 2205
Therefore, the value for common factors is 2205.
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 = 16910579980350/(1x2205)
LCM = 16910579980350/2205
LCM = 7669197270
Thus, we can understand that the LCM of 329,315,978,681,245 is 7669197270.
