Given numbers are 865,253,388,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,253,388,121 is 934030460.
Find LCM of 865,253,388,121 with Prime Factorization
11 | 865, 253, 388, 121 |
865, 23, 388, 11 |
Multiply the prime numbers at the bottom and the left side.
11 x 865 x 23 x 388 x 11 = 934030460
Therefore, the lowest common multiple of 865,253,388,121 is 934030460.
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.
865 x 253 x 388 x 121 = 10274335060
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.
865 : 1, 5, 173, 865
253 : 1, 11, 23, 253
388 : 1, 2, 4, 97, 194, 388
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,253,388,121, is 1.
Now, the common factors can be found like this.
865:5x 173
253:11x 23
388:2x 2x 97
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.
11 = 11
Therefore, the value for common factors is 11.
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 = 10274335060/(1x11)
LCM = 10274335060/11
LCM = 934030460
Thus, we can understand that the LCM of 865,253,388,121 is 934030460.
