Find LCM of 392,458,196,248,922 with Prime Factorization
| 2 | 392, 458, 196, 248, 922 |
| 2 | 196, 229, 98, 124, 461 |
| 2 | 49, 229, 98, 62, 461 |
| 7 | 49, 229, 49, 31, 461 |
| 7 | 7, 229, 7, 31, 461 |
| 1, 229, 1, 31, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 1 x 229 x 1 x 31 x 461 = 1282874488
Therefore, the lowest common multiple of 392,458,196,248,922 is 1282874488.
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.
392 x 458 x 196 x 248 x 922 = 8046188788736
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
458 : 1, 2, 229, 458
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
248 : 1, 2, 4, 8, 31, 62, 124, 248
922 : 1, 2, 461, 922
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,458,196,248,922, is 2.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
458:2x 229
196:2x 2x 7x 7
248:2x 2x 2x 31
922:2x 461
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 2x 7x 7 = 3136
Therefore, the value for common factors is 3136.
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 = 8046188788736/(2x3136)
LCM = 8046188788736/6272
LCM = 1282874488
Thus, we can understand that the LCM of 392,458,196,248,922 is 1282874488.
