Given numbers are 55,78,44,99,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 55,78,44,99,822 is 3526380.
Find LCM of 55,78,44,99,822 with Prime Factorization
| 2 | 55, 78, 44, 99, 822 |
| 3 | 55, 39, 22, 99, 411 |
| 11 | 55, 13, 22, 33, 137 |
| 5, 13, 2, 3, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 5 x 13 x 2 x 3 x 137 = 3526380
Therefore, the lowest common multiple of 55,78,44,99,822 is 3526380.
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.
55 x 78 x 44 x 99 x 822 = 15360911280
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.
55 : 1, 5, 11, 55
78 : 1, 2, 3, 6, 13, 26, 39, 78
44 : 1, 2, 4, 11, 22, 44
99 : 1, 3, 9, 11, 33, 99
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 55,78,44,99,822, is 1.
Now, the common factors can be found like this.
55:5x 11
78:2x 3x 13
44:2x 2x 11
99:3x 3x 11
822:2x 3x 137
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 3x 3x 11x 11 = 4356
Therefore, the value for common factors is 4356.
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 = 15360911280/(1x4356)
LCM = 15360911280/4356
LCM = 3526380
Thus, we can understand that the LCM of 55,78,44,99,822 is 3526380.
