Given numbers are 900,888,778,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 900,888,778,243 is 699499800.
Find LCM of 900,888,778,243 with Prime Factorization
| 2 | 900, 888, 778, 243 |
| 2 | 450, 444, 389, 243 |
| 3 | 225, 222, 389, 243 |
| 3 | 75, 74, 389, 81 |
| 25, 74, 389, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 25 x 74 x 389 x 27 = 699499800
Therefore, the lowest common multiple of 900,888,778,243 is 699499800.
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.
900 x 888 x 778 x 243 = 151091956800
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
778 : 1, 2, 389, 778
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,888,778,243, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
888:2x 2x 2x 3x 37
778:2x 389
243:3x 3x 3x 3x 3
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 151091956800/(1x216)
LCM = 151091956800/216
LCM = 699499800
Thus, we can understand that the LCM of 900,888,778,243 is 699499800.
