Given numbers are 869,209,946,471
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,209,946,471 is 668794566.
Find LCM of 869,209,946,471 with Prime Factorization
| 11 | 869, 209, 946, 471 |
| 79, 19, 86, 471 |
Multiply the prime numbers at the bottom and the left side.
11 x 79 x 19 x 86 x 471 = 668794566
Therefore, the lowest common multiple of 869,209,946,471 is 668794566.
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.
869 x 209 x 946 x 471 = 80924142486
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.
869 : 1, 11, 79, 869
209 : 1, 11, 19, 209
946 : 1, 2, 11, 22, 43, 86, 473, 946
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,209,946,471, is 1.
Now, the common factors can be found like this.
869:11x 79
209:11x 19
946:2x 11x 43
471:3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 80924142486/(1x121)
LCM = 80924142486/121
LCM = 668794566
Thus, we can understand that the LCM of 869,209,946,471 is 668794566.
