Given numbers are 759,399,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,399,121 is 1110417.
Find LCM of 759,399,121 with Prime Factorization
| 3 | 759, 399, 121 |
| 11 | 253, 133, 121 |
| 23, 133, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 133 x 11 = 1110417
Therefore, the lowest common multiple of 759,399,121 is 1110417.
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.
759 x 399 x 121 = 36643761
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
399 : 1, 3, 7, 19, 21, 57, 133, 399
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,399,121, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
399:3x 7x 19
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.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 36643761/(1x33)
LCM = 36643761/33
LCM = 1110417
Thus, we can understand that the LCM of 759,399,121 is 1110417.
