Given numbers are 496,646,186,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,646,186,538 is 129287856.
Find LCM of 496,646,186,538 with Prime Factorization
| 2 | 496, 646, 186, 538 |
| 31 | 248, 323, 93, 269 |
| 8, 323, 3, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 8 x 323 x 3 x 269 = 129287856
Therefore, the lowest common multiple of 496,646,186,538 is 129287856.
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.
496 x 646 x 186 x 538 = 32063388288
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
646 : 1, 2, 17, 19, 34, 38, 323, 646
186 : 1, 2, 3, 6, 31, 62, 93, 186
538 : 1, 2, 269, 538
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,646,186,538, is 2.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
646:2x 17x 19
186:2x 3x 31
538:2x 269
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 31 = 124
Therefore, the value for common factors is 124.
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 = 32063388288/(2x124)
LCM = 32063388288/248
LCM = 129287856
Thus, we can understand that the LCM of 496,646,186,538 is 129287856.
