Given numbers are 181,374,794,794,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,374,794,794,138 is 1854341742.
Find LCM of 181,374,794,794,138 with Prime Factorization
2 | 181, 374, 794, 794, 138 |
397 | 181, 187, 397, 397, 69 |
181, 187, 1, 1, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 397 x 181 x 187 x 1 x 1 x 69 = 1854341742
Therefore, the lowest common multiple of 181,374,794,794,138 is 1854341742.
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.
181 x 374 x 794 x 794 x 138 = 5889389372592
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.
181 : 1, 181
374 : 1, 2, 11, 17, 22, 34, 187, 374
794 : 1, 2, 397, 794
794 : 1, 2, 397, 794
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,374,794,794,138, is 1.
Now, the common factors can be found like this.
181:181
374:2x 11x 17
794:2x 397
794:2x 397
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 397 = 3176
Therefore, the value for common factors is 3176.
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 = 5889389372592/(1x3176)
LCM = 5889389372592/3176
LCM = 1854341742
Thus, we can understand that the LCM of 181,374,794,794,138 is 1854341742.
