Given numbers are 686,358,899,341,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,358,899,341,279 is 10928788794.
Find LCM of 686,358,899,341,279 with Prime Factorization
| 2 | 686, 358, 899, 341, 279 |
| 31 | 343, 179, 899, 341, 279 |
| 343, 179, 29, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 343 x 179 x 29 x 11 x 9 = 10928788794
Therefore, the lowest common multiple of 686,358,899,341,279 is 10928788794.
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.
686 x 358 x 899 x 341 x 279 = 21005132062068
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
358 : 1, 2, 179, 358
899 : 1, 29, 31, 899
341 : 1, 11, 31, 341
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,358,899,341,279, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
358:2x 179
899:29x 31
341:11x 31
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31x 31 = 1922
Therefore, the value for common factors is 1922.
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 = 21005132062068/(1x1922)
LCM = 21005132062068/1922
LCM = 10928788794
Thus, we can understand that the LCM of 686,358,899,341,279 is 10928788794.
