Given numbers are 819,608,766,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,608,766,978 is 31086645408.
Find LCM of 819,608,766,978 with Prime Factorization
2 | 819, 608, 766, 978 |
3 | 819, 304, 383, 489 |
273, 304, 383, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 273 x 304 x 383 x 163 = 31086645408
Therefore, the lowest common multiple of 819,608,766,978 is 31086645408.
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.
819 x 608 x 766 x 978 = 373039744896
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
766 : 1, 2, 383, 766
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,608,766,978, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
608:2x 2x 2x 2x 2x 19
766:2x 383
978:2x 3x 163
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 = 373039744896/(1x12)
LCM = 373039744896/12
LCM = 31086645408
Thus, we can understand that the LCM of 819,608,766,978 is 31086645408.
