Given numbers are 685,649,137,465,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,649,137,465,777 is 10708237155.
Find LCM of 685,649,137,465,777 with Prime Factorization
| 3 | 685, 649, 137, 465, 777 |
| 5 | 685, 649, 137, 155, 259 |
| 137 | 137, 649, 137, 31, 259 |
| 1, 649, 1, 31, 259 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 137 x 1 x 649 x 1 x 31 x 259 = 10708237155
Therefore, the lowest common multiple of 685,649,137,465,777 is 10708237155.
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.
685 x 649 x 137 x 465 x 777 = 22005427353525
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.
685 : 1, 5, 137, 685
649 : 1, 11, 59, 649
137 : 1, 137
465 : 1, 3, 5, 15, 31, 93, 155, 465
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,649,137,465,777, is 1.
Now, the common factors can be found like this.
685:5x 137
649:11x 59
137:137
465:3x 5x 31
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 137 = 2055
Therefore, the value for common factors is 2055.
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 = 22005427353525/(1x2055)
LCM = 22005427353525/2055
LCM = 10708237155
Thus, we can understand that the LCM of 685,649,137,465,777 is 10708237155.
