Given numbers are 379,507,978,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,507,978,819 is 1315479438.
Find LCM of 379,507,978,819 with Prime Factorization
3 | 379, 507, 978, 819 |
13 | 379, 169, 326, 273 |
379, 13, 326, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 379 x 13 x 326 x 21 = 1315479438
Therefore, the lowest common multiple of 379,507,978,819 is 1315479438.
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.
379 x 507 x 978 x 819 = 153911094246
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.
379 : 1, 379
507 : 1, 3, 13, 39, 169, 507
978 : 1, 2, 3, 6, 163, 326, 489, 978
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,507,978,819, is 1.
Now, the common factors can be found like this.
379:379
507:3x 13x 13
978:2x 3x 163
819:3x 3x 7x 13
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 13 = 117
Therefore, the value for common factors is 117.
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 = 153911094246/(1x117)
LCM = 153911094246/117
LCM = 1315479438
Thus, we can understand that the LCM of 379,507,978,819 is 1315479438.
