Given numbers are 211,978,629,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,978,629,663 is 1687389366.
Find LCM of 211,978,629,663 with Prime Factorization
| 3 | 211, 978, 629, 663 |
| 17 | 211, 326, 629, 221 |
| 211, 326, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 211 x 326 x 37 x 13 = 1687389366
Therefore, the lowest common multiple of 211,978,629,663 is 1687389366.
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.
211 x 978 x 629 x 663 = 86056857666
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.
211 : 1, 211
978 : 1, 2, 3, 6, 163, 326, 489, 978
629 : 1, 17, 37, 629
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,978,629,663, is 1.
Now, the common factors can be found like this.
211:211
978:2x 3x 163
629:17x 37
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 86056857666/(1x51)
LCM = 86056857666/51
LCM = 1687389366
Thus, we can understand that the LCM of 211,978,629,663 is 1687389366.
