Find LCM of 686,224,336,273 with Prime Factorization
2 | 686, 224, 336, 273 |
2 | 343, 112, 168, 273 |
2 | 343, 56, 84, 273 |
2 | 343, 28, 42, 273 |
3 | 343, 14, 21, 273 |
7 | 343, 14, 7, 91 |
49, 2, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 49 x 2 x 1 x 13 = 428064
Therefore, the lowest common multiple of 686,224,336,273 is 428064.
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 224 x 336 x 273 = 14095291392
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
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
273 : 1, 3, 7, 13, 21, 39, 91, 273
7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,224,336,273, is 7.
Now, the common factors can be found like this.
686:2x 7x 7x 7
224:2x 2x 2x 2x 2x 7
336:2x 2x 2x 2x 3x 7
273:3x 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.
2x 2x 2x 2x 2x 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 14095291392/(7x4704)
LCM = 14095291392/32928
LCM = 428064
Thus, we can understand that the LCM of 686,224,336,273 is 428064.
