Given numbers are 391,874,121,359
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,874,121,359 is 645416662.
Find LCM of 391,874,121,359 with Prime Factorization
| 23 | 391, 874, 121, 359 |
| 17, 38, 121, 359 |
Multiply the prime numbers at the bottom and the left side.
23 x 17 x 38 x 121 x 359 = 645416662
Therefore, the lowest common multiple of 391,874,121,359 is 645416662.
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.
391 x 874 x 121 x 359 = 14844583226
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.
391 : 1, 17, 23, 391
874 : 1, 2, 19, 23, 38, 46, 437, 874
121 : 1, 11, 121
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,874,121,359, is 1.
Now, the common factors can be found like this.
391:17x 23
874:2x 19x 23
121:11x 11
359:359
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 14844583226/(1x23)
LCM = 14844583226/23
LCM = 645416662
Thus, we can understand that the LCM of 391,874,121,359 is 645416662.
