Given numbers are 171,139,629,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,139,629,777 is 104654907.
Find LCM of 171,139,629,777 with Prime Factorization
| 3 | 171, 139, 629, 777 |
| 37 | 57, 139, 629, 259 |
| 57, 139, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 57 x 139 x 17 x 7 = 104654907
Therefore, the lowest common multiple of 171,139,629,777 is 104654907.
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.
171 x 139 x 629 x 777 = 11616694677
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.
171 : 1, 3, 9, 19, 57, 171
139 : 1, 139
629 : 1, 17, 37, 629
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 171,139,629,777, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
139:139
629:17x 37
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 37 = 111
Therefore, the value for common factors is 111.
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 = 11616694677/(1x111)
LCM = 11616694677/111
LCM = 104654907
Thus, we can understand that the LCM of 171,139,629,777 is 104654907.
