Given numbers are 227,978,897,252,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 227,978,897,252,987 is 131033713356.
Find LCM of 227,978,897,252,987 with Prime Factorization
| 2 | 227, 978, 897, 252, 987 |
| 3 | 227, 489, 897, 126, 987 |
| 7 | 227, 163, 299, 42, 329 |
| 227, 163, 299, 6, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 227 x 163 x 299 x 6 x 47 = 131033713356
Therefore, the lowest common multiple of 227,978,897,252,987 is 131033713356.
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.
227 x 978 x 897 x 252 x 987 = 49530743648568
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.
227 : 1, 227
978 : 1, 2, 3, 6, 163, 326, 489, 978
897 : 1, 3, 13, 23, 39, 69, 299, 897
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,978,897,252,987, is 1.
Now, the common factors can be found like this.
227:227
978:2x 3x 163
897:3x 13x 23
252:2x 2x 3x 3x 7
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 49530743648568/(1x378)
LCM = 49530743648568/378
LCM = 131033713356
Thus, we can understand that the LCM of 227,978,897,252,987 is 131033713356.
