Given numbers are 177,403,491,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,403,491,961 is 1085729151.
Find LCM of 177,403,491,961 with Prime Factorization
| 31 | 177, 403, 491, 961 |
| 177, 13, 491, 31 |
Multiply the prime numbers at the bottom and the left side.
31 x 177 x 13 x 491 x 31 = 1085729151
Therefore, the lowest common multiple of 177,403,491,961 is 1085729151.
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.
177 x 403 x 491 x 961 = 33657603681
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.
177 : 1, 3, 59, 177
403 : 1, 13, 31, 403
491 : 1, 491
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,403,491,961, is 1.
Now, the common factors can be found like this.
177:3x 59
403:13x 31
491:491
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31 = 31
Therefore, the value for common factors is 31.
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 = 33657603681/(1x31)
LCM = 33657603681/31
LCM = 1085729151
Thus, we can understand that the LCM of 177,403,491,961 is 1085729151.
