Given numbers are 819,397,546,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,397,546,769 is 500069934.
Find LCM of 819,397,546,769 with Prime Factorization
3 | 819, 397, 546, 769 |
7 | 273, 397, 182, 769 |
13 | 39, 397, 26, 769 |
3, 397, 2, 769 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 3 x 397 x 2 x 769 = 500069934
Therefore, the lowest common multiple of 819,397,546,769 is 500069934.
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 397 x 546 x 769 = 136519091982
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
397 : 1, 397
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,397,546,769, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
397:397
546:2x 3x 7x 13
769:769
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 136519091982/(1x273)
LCM = 136519091982/273
LCM = 500069934
Thus, we can understand that the LCM of 819,397,546,769 is 500069934.
