Given numbers are 198,827,780,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,827,780,144 is 85147920.
Find LCM of 198,827,780,144 with Prime Factorization
| 2 | 198, 827, 780, 144 |
| 2 | 99, 827, 390, 72 |
| 3 | 99, 827, 195, 36 |
| 3 | 33, 827, 65, 12 |
| 11, 827, 65, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 827 x 65 x 4 = 85147920
Therefore, the lowest common multiple of 198,827,780,144 is 85147920.
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.
198 x 827 x 780 x 144 = 18391950720
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
827 : 1, 827
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,827,780,144, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
827:827
780:2x 2x 3x 5x 13
144:2x 2x 2x 2x 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 = 18391950720/(1x216)
LCM = 18391950720/216
LCM = 85147920
Thus, we can understand that the LCM of 198,827,780,144 is 85147920.
