Given numbers are 978,929,424,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,929,424,261 is 16757517528.
Find LCM of 978,929,424,261 with Prime Factorization
| 2 | 978, 929, 424, 261 |
| 3 | 489, 929, 212, 261 |
| 163, 929, 212, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 929 x 212 x 87 = 16757517528
Therefore, the lowest common multiple of 978,929,424,261 is 16757517528.
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 929 x 424 x 261 = 100545105168
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
929 : 1, 929
424 : 1, 2, 4, 8, 53, 106, 212, 424
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,929,424,261, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
929:929
424:2x 2x 2x 53
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 100545105168/(1x6)
LCM = 100545105168/6
LCM = 16757517528
Thus, we can understand that the LCM of 978,929,424,261 is 16757517528.
