Given numbers are 911,513,686,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 911,513,686,665 is 1602986490.
Find LCM of 911,513,686,665 with Prime Factorization
| 7 | 911, 513, 686, 665 |
| 19 | 911, 513, 98, 95 |
| 911, 27, 98, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 911 x 27 x 98 x 5 = 1602986490
Therefore, the lowest common multiple of 911,513,686,665 is 1602986490.
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.
911 x 513 x 686 x 665 = 213197203170
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.
911 : 1, 911
513 : 1, 3, 9, 19, 27, 57, 171, 513
686 : 1, 2, 7, 14, 49, 98, 343, 686
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,513,686,665, is 1.
Now, the common factors can be found like this.
911:911
513:3x 3x 3x 19
686:2x 7x 7x 7
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 213197203170/(1x133)
LCM = 213197203170/133
LCM = 1602986490
Thus, we can understand that the LCM of 911,513,686,665 is 1602986490.
