Given numbers are 867,521,209,777,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,521,209,777,966 is 1124762174382.
Find LCM of 867,521,209,777,966 with Prime Factorization
| 3 | 867, 521, 209, 777, 966 |
| 7 | 289, 521, 209, 259, 322 |
| 289, 521, 209, 37, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 289 x 521 x 209 x 37 x 46 = 1124762174382
Therefore, the lowest common multiple of 867,521,209,777,966 is 1124762174382.
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.
867 x 521 x 209 x 777 x 966 = 70860016986066
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.
867 : 1, 3, 17, 51, 289, 867
521 : 1, 521
209 : 1, 11, 19, 209
777 : 1, 3, 7, 21, 37, 111, 259, 777
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,521,209,777,966, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
521:521
209:11x 19
777:3x 7x 37
966:2x 3x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 70860016986066/(1x63)
LCM = 70860016986066/63
LCM = 1124762174382
Thus, we can understand that the LCM of 867,521,209,777,966 is 1124762174382.
