Given numbers are 216,978,451,224
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 216,978,451,224 is 444606624.
Find LCM of 216,978,451,224 with Prime Factorization
| 2 | 216, 978, 451, 224 |
| 2 | 108, 489, 451, 112 |
| 2 | 54, 489, 451, 56 |
| 3 | 27, 489, 451, 28 |
| 9, 163, 451, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 9 x 163 x 451 x 28 = 444606624
Therefore, the lowest common multiple of 216,978,451,224 is 444606624.
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.
216 x 978 x 451 x 224 = 21341117952
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
978 : 1, 2, 3, 6, 163, 326, 489, 978
451 : 1, 11, 41, 451
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,978,451,224, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
978:2x 3x 163
451:11x 41
224:2x 2x 2x 2x 2x 7
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 21341117952/(1x48)
LCM = 21341117952/48
LCM = 444606624
Thus, we can understand that the LCM of 216,978,451,224 is 444606624.
