Find LCM of 892,351,988,342 with Prime Factorization
| 2 | 892, 351, 988, 342 |
| 2 | 446, 351, 494, 171 |
| 3 | 223, 351, 247, 171 |
| 3 | 223, 117, 247, 57 |
| 13 | 223, 39, 247, 19 |
| 19 | 223, 3, 19, 19 |
| 223, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 19 x 223 x 3 x 1 x 1 = 5948748
Therefore, the lowest common multiple of 892,351,988,342 is 5948748.
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.
892 x 351 x 988 x 342 = 105792534432
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.
892 : 1, 2, 4, 223, 446, 892
351 : 1, 3, 9, 13, 27, 39, 117, 351
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,351,988,342, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
351:3x 3x 3x 13
988:2x 2x 13x 19
342:2x 3x 3x 19
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 3x 3x 13x 19 = 17784
Therefore, the value for common factors is 17784.
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 = 105792534432/(1x17784)
LCM = 105792534432/17784
LCM = 5948748
Thus, we can understand that the LCM of 892,351,988,342 is 5948748.
