Given numbers are 392,548,211,286,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,548,211,286,869 is 128012452568.
Find LCM of 392,548,211,286,869 with Prime Factorization
| 2 | 392, 548, 211, 286, 869 |
| 2 | 196, 274, 211, 143, 869 |
| 11 | 98, 137, 211, 143, 869 |
| 98, 137, 211, 13, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 98 x 137 x 211 x 13 x 79 = 128012452568
Therefore, the lowest common multiple of 392,548,211,286,869 is 128012452568.
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 548 x 211 x 286 x 869 = 11265095825984
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
548 : 1, 2, 4, 137, 274, 548
211 : 1, 211
286 : 1, 2, 11, 13, 22, 26, 143, 286
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,548,211,286,869, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
548:2x 2x 137
211:211
286:2x 11x 13
869:11x 79
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 11 = 88
Therefore, the value for common factors is 88.
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 = 11265095825984/(1x88)
LCM = 11265095825984/88
LCM = 128012452568
Thus, we can understand that the LCM of 392,548,211,286,869 is 128012452568.
