Given numbers are 686,269,196,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,269,196,374 is 69015716.
Find LCM of 686,269,196,374 with Prime Factorization
| 2 | 686, 269, 196, 374 |
| 7 | 343, 269, 98, 187 |
| 7 | 49, 269, 14, 187 |
| 7, 269, 2, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 7 x 269 x 2 x 187 = 69015716
Therefore, the lowest common multiple of 686,269,196,374 is 69015716.
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 269 x 196 x 374 = 13527080336
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
269 : 1, 269
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,269,196,374, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
269:269
196:2x 2x 7x 7
374:2x 11x 17
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 13527080336/(1x196)
LCM = 13527080336/196
LCM = 69015716
Thus, we can understand that the LCM of 686,269,196,374 is 69015716.
