Given numbers are 378,979,343,319
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,979,343,319 is 525858102.
Find LCM of 378,979,343,319 with Prime Factorization
| 7 | 378, 979, 343, 319 |
| 11 | 54, 979, 49, 319 |
| 54, 89, 49, 29 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 54 x 89 x 49 x 29 = 525858102
Therefore, the lowest common multiple of 378,979,343,319 is 525858102.
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.
378 x 979 x 343 x 319 = 40491073854
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
979 : 1, 11, 89, 979
343 : 1, 7, 49, 343
319 : 1, 11, 29, 319
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,979,343,319, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
979:11x 89
343:7x 7x 7
319:11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 40491073854/(1x77)
LCM = 40491073854/77
LCM = 525858102
Thus, we can understand that the LCM of 378,979,343,319 is 525858102.
