Given numbers are 561,669,300,260
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,669,300,260 is 162633900.
Find LCM of 561,669,300,260 with Prime Factorization
| 2 | 561, 669, 300, 260 |
| 2 | 561, 669, 150, 130 |
| 3 | 561, 669, 75, 65 |
| 5 | 187, 223, 25, 65 |
| 187, 223, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 187 x 223 x 5 x 13 = 162633900
Therefore, the lowest common multiple of 561,669,300,260 is 162633900.
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.
561 x 669 x 300 x 260 = 29274102000
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
669 : 1, 3, 223, 669
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,669,300,260, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
669:3x 223
300:2x 2x 3x 5x 5
260:2x 2x 5x 13
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 5 = 180
Therefore, the value for common factors is 180.
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 = 29274102000/(1x180)
LCM = 29274102000/180
LCM = 162633900
Thus, we can understand that the LCM of 561,669,300,260 is 162633900.
