Given numbers are 664,681,949,945,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 664,681,949,945,711 is 10678716299160.
Find LCM of 664,681,949,945,711 with Prime Factorization
| 3 | 664, 681, 949, 945, 711 |
| 3 | 664, 227, 949, 315, 237 |
| 664, 227, 949, 105, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 664 x 227 x 949 x 105 x 79 = 10678716299160
Therefore, the lowest common multiple of 664,681,949,945,711 is 10678716299160.
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.
664 x 681 x 949 x 945 x 711 = 288325340077320
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
681 : 1, 3, 227, 681
949 : 1, 13, 73, 949
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,681,949,945,711, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
681:3x 227
949:13x 73
945:3x 3x 3x 5x 7
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 288325340077320/(1x27)
LCM = 288325340077320/27
LCM = 10678716299160
Thus, we can understand that the LCM of 664,681,949,945,711 is 10678716299160.
