Given numbers are 290,771,978,173,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,771,978,173,747 is 1569948588090.
Find LCM of 290,771,978,173,747 with Prime Factorization
| 2 | 290, 771, 978, 173, 747 |
| 3 | 145, 771, 489, 173, 747 |
| 145, 257, 163, 173, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 145 x 257 x 163 x 173 x 249 = 1569948588090
Therefore, the lowest common multiple of 290,771,978,173,747 is 1569948588090.
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.
290 x 771 x 978 x 173 x 747 = 28259074585620
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
771 : 1, 3, 257, 771
978 : 1, 2, 3, 6, 163, 326, 489, 978
173 : 1, 173
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,771,978,173,747, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
771:3x 257
978:2x 3x 163
173:173
747:3x 3x 83
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 3 = 18
Therefore, the value for common factors is 18.
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 = 28259074585620/(1x18)
LCM = 28259074585620/18
LCM = 1569948588090
Thus, we can understand that the LCM of 290,771,978,173,747 is 1569948588090.
