Given numbers are 66,30,22,75,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 66,30,22,75,557 is 919050.
Find LCM of 66,30,22,75,557 with Prime Factorization
| 2 | 66, 30, 22, 75, 557 |
| 3 | 33, 15, 11, 75, 557 |
| 5 | 11, 5, 11, 25, 557 |
| 11 | 11, 1, 11, 5, 557 |
| 1, 1, 1, 5, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 1 x 1 x 1 x 5 x 557 = 919050
Therefore, the lowest common multiple of 66,30,22,75,557 is 919050.
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.
66 x 30 x 22 x 75 x 557 = 1819719000
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.
66 : 1, 2, 3, 6, 11, 22, 33, 66
30 : 1, 2, 3, 5, 6, 10, 15, 30
22 : 1, 2, 11, 22
75 : 1, 3, 5, 15, 25, 75
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 66,30,22,75,557, is 1.
Now, the common factors can be found like this.
66:2x 3x 11
30:2x 3x 5
22:2x 11
75:3x 5x 5
557:557
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 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 1819719000/(1x1980)
LCM = 1819719000/1980
LCM = 919050
Thus, we can understand that the LCM of 66,30,22,75,557 is 919050.
