Given numbers are 978,278,649,722,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,278,649,722,867 is 9204567703782.
Find LCM of 978,278,649,722,867 with Prime Factorization
| 2 | 978, 278, 649, 722, 867 |
| 3 | 489, 139, 649, 361, 867 |
| 163, 139, 649, 361, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 139 x 649 x 361 x 289 = 9204567703782
Therefore, the lowest common multiple of 978,278,649,722,867 is 9204567703782.
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.
978 x 278 x 649 x 722 x 867 = 110454812445384
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
278 : 1, 2, 139, 278
649 : 1, 11, 59, 649
722 : 1, 2, 19, 38, 361, 722
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,278,649,722,867, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
278:2x 139
649:11x 59
722:2x 19x 19
867:3x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 110454812445384/(1x12)
LCM = 110454812445384/12
LCM = 9204567703782
Thus, we can understand that the LCM of 978,278,649,722,867 is 9204567703782.
