Given numbers are 428,248,713,192
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,248,713,192 is 14647872.
Find LCM of 428,248,713,192 with Prime Factorization
| 2 | 428, 248, 713, 192 |
| 2 | 214, 124, 713, 96 |
| 2 | 107, 62, 713, 48 |
| 31 | 107, 31, 713, 24 |
| 107, 1, 23, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 107 x 1 x 23 x 24 = 14647872
Therefore, the lowest common multiple of 428,248,713,192 is 14647872.
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.
428 x 248 x 713 x 192 = 14530689024
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.
428 : 1, 2, 4, 107, 214, 428
248 : 1, 2, 4, 8, 31, 62, 124, 248
713 : 1, 23, 31, 713
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,248,713,192, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
248:2x 2x 2x 31
713:23x 31
192:2x 2x 2x 2x 2x 2x 3
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 31 = 992
Therefore, the value for common factors is 992.
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 = 14530689024/(1x992)
LCM = 14530689024/992
LCM = 14647872
Thus, we can understand that the LCM of 428,248,713,192 is 14647872.
