Given numbers are 961,864,772,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,864,772,121 is 19390089312.
Find LCM of 961,864,772,121 with Prime Factorization
| 2 | 961, 864, 772, 121 |
| 2 | 961, 432, 386, 121 |
| 961, 216, 193, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 961 x 216 x 193 x 121 = 19390089312
Therefore, the lowest common multiple of 961,864,772,121 is 19390089312.
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 864 x 772 x 121 = 77560357248
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
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
772 : 1, 2, 4, 193, 386, 772
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,864,772,121, is 1.
Now, the common factors can be found like this.
961:31x 31
864:2x 2x 2x 2x 2x 3x 3x 3
772:2x 2x 193
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 77560357248/(1x4)
LCM = 77560357248/4
LCM = 19390089312
Thus, we can understand that the LCM of 961,864,772,121 is 19390089312.
