Given numbers are 398,329,791,427,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,329,791,427,305 is 4512916030.
Find LCM of 398,329,791,427,305 with Prime Factorization
7 | 398, 329, 791, 427, 305 |
61 | 398, 47, 113, 61, 305 |
398, 47, 113, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 61 x 398 x 47 x 113 x 1 x 5 = 4512916030
Therefore, the lowest common multiple of 398,329,791,427,305 is 4512916030.
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.
398 x 329 x 791 x 427 x 305 = 13489106013670
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.
398 : 1, 2, 199, 398
329 : 1, 7, 47, 329
791 : 1, 7, 113, 791
427 : 1, 7, 61, 427
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,329,791,427,305, is 1.
Now, the common factors can be found like this.
398:2x 199
329:7x 47
791:7x 113
427:7x 61
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 61 = 2989
Therefore, the value for common factors is 2989.
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 = 13489106013670/(1x2989)
LCM = 13489106013670/2989
LCM = 4512916030
Thus, we can understand that the LCM of 398,329,791,427,305 is 4512916030.
