Given numbers are 961,682,449,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,682,449,129 is 1224565782.
Find LCM of 961,682,449,129 with Prime Factorization
| 31 | 961, 682, 449, 129 |
| 31, 22, 449, 129 |
Multiply the prime numbers at the bottom and the left side.
31 x 31 x 22 x 449 x 129 = 1224565782
Therefore, the lowest common multiple of 961,682,449,129 is 1224565782.
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.
961 x 682 x 449 x 129 = 37961539242
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.
961 : 1, 31, 961
682 : 1, 2, 11, 22, 31, 62, 341, 682
449 : 1, 449
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,682,449,129, is 1.
Now, the common factors can be found like this.
961:31x 31
682:2x 11x 31
449:449
129:3x 43
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 = 37961539242/(1x31)
LCM = 37961539242/31
LCM = 1224565782
Thus, we can understand that the LCM of 961,682,449,129 is 1224565782.
