Given numbers are 660,700,303,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,700,303,909 is 6999300.
Find LCM of 660,700,303,909 with Prime Factorization
| 2 | 660, 700, 303, 909 |
| 2 | 330, 350, 303, 909 |
| 3 | 165, 175, 303, 909 |
| 5 | 55, 175, 101, 303 |
| 101 | 11, 35, 101, 303 |
| 11, 35, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 101 x 11 x 35 x 1 x 3 = 6999300
Therefore, the lowest common multiple of 660,700,303,909 is 6999300.
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.
660 x 700 x 303 x 909 = 127247274000
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
303 : 1, 3, 101, 303
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,700,303,909, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
700:2x 2x 5x 5x 7
303:3x 101
909:3x 3x 101
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 101 = 18180
Therefore, the value for common factors is 18180.
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 = 127247274000/(1x18180)
LCM = 127247274000/18180
LCM = 6999300
Thus, we can understand that the LCM of 660,700,303,909 is 6999300.
